| name = LOC105377021 | image = | Symbol = UNQ6490, PRO21339, (LOC389102, YPLR6490) }}LOC105377021 is a protein which in humans is encoded by the LOC105377021 gene.[1][2] LOC105377021 exhibits expressional pathology related to breast cancer, specifically triple negative breast cancer.[3][4] LOC105377021 contains a serine rich region in addition to predicted alpha helix motifs.[5][2] Gene and mRNALOC105377021 localizes to Homo sapiens chromosome 3 (3p2; antisense strand), approximate to the reading frame of TRIM71.[2][3][4] The corresponding gene has 2,473 nucleotides.[2] There is one exon in the LOC105377021p mRNA.[2] There is no predicted alternative splicing on the NCBI gene database.[2] ProteinProtein Primary StructureThe figure below shows the basic primary protein structure, with N-terminus and C-terminus in their respective annotations. The orange domain is a predicted nuclear localization sequence, while the blue domain is the remainder of the LOC105377021 exon.[13]
Protein Secondary StructureAccording to Ali2D (a multiple sequence alignment structural predictor for proteins), LOC105377021 is predicted to form mostly alpha helix (see red highlight, blue highlight is for Beta Sheet).[8] Protein Tertiary StructureLOC105377021 has a prominent, C-terminus repeat of serine residues, potentially for disulfide bonding.[2] One disulfide bond (139-148) was predicted by DISULFIDE software.[9] Additionally, the I TASSER profile shows several alpha helices in a variety of different colors, in addition to potential turn motifs (see I TASSER 3D Prediction of LOC105377021).[10] Protein Modifications and LocalizationA predicted protein modification of LOC105377021 is phosphorylation, with sites throughout the protein, including the serine rich construct near the C-terminus of the protein.[11][12] In addition, there is predicted evidence of O-Linked β-N-acetylglucosamine supplements in the C terminal region.[13][14] There is predicted evidence for a nuclear localization sequence oriented at the N-terminal, provided by PSORT with partial support by PHOBIUS software.[15][16] Microarray Expression Pattern and PathologyBasic Expression and Breast CancerCompared to the average expression of human protein, LOC105377021 is expressed at 0.9%, which is classified as low.[3] In humans: cranial, intestinal, ovarian, renal, and testicular tissues corroborate this trend.[3] Microarray data posits the expression of LOC105377021 in certain breast cancer tissues, including metastases to lymphatic and lung tissue.[17] There is potential evidence for higher expression of LOC105377021 during Triple Negative Breast Cancer, which overshadows normal secretion levels for said protein.[18] The figure below shows a potential trend line for this pattern (shown in green, with the triple negative microarray on the left). As the figure legend states, the red bars refer to the left axis for sample counts, whereas the blue dots show the percentage of LOC105377021 expression within each sample (the right axis).

Brain Tissue ExpressionSeven key brain tissues express LOC105377021 according to an Allen Brain Atlas probe.[19] The temporal lobe, parietal lobe, cingulate gyrus, parahippocampal gyrus, and insula are five overarching regions of the seven brain tissues where expression was highlighted. The annotated figures below serve as fairly holistic representations of cranial expression in the context of LOC105377021. Light blue shaded regions posit more dense expression of LOC105377021, where as darker green and brighter red show less and least amounts of expression respectively. All seven expression areas, including the middle temporal gyrus, the short insular gyrus, the postcentral gyrus, the cingulate gyrus, the inferior temporal gyrus, the parahippocampal gyrus, and the superior temporal gyrus are depicted in Allen Brain Atlas profiles below.

Evolutionary Relationships and HomologyOrthologsThe Basic Local Alignment Sequence Tool (BLAST) shows that LOC105377021 orthologs are largely homogenous and mammalian.[20] Important orthologs are summarized into three categories: primates, aquatic mammals, and ferrets/ferret-like animals. Pongo abelii and Tursiops truncatus are the most distant and related orthologs respectively. The river dolphin is the first ortholog to detach from the 80% plus similarity cohort. The following includes a list of select orthologs found:
Pace of EvolutionThe pace of evolution of LOC105377021 upon its inception (in humans) is modeled to be slow. This speed is relative to cytochrome c 6A1 and Alpha fibrinogen using corrected divergence methods. The corrected divergences graph above shows three lines: Alpha Fibrinogen in Red, LOC Ortholog (aka LOC105377021) in blue, and Cytochrome c 6A1 in green. These lines associate with evolutionary pace in LOC105377021, as tested using a corrected divergence genomic analysis. Single Nucleotide PolymorphismsThe following diagram shows single nucleotide polymorphisms (SNP's) in various regions of the protein. SNP's are highlighted green, with SNP coding on the right hand coding for switches in amino acids.[22]
Promoter and Gene RegulationAccording to Genomatix, LOC389102 (synonym to LOC105377021) is proximate to a 601 base pair promoter and a 5'UTR 129 base pairs long consecutively.[2][23] Genomatix predicts several transcription factors in general. Two select factors predicted include Gli3 and E2F1.[23] References1. ^{{Cite web|url=https://www.genenames.org|title=HGNC database of human gene names {{!}} HUGO Gene Nomenclature Committee|website=www.genenames.org|access-date=2016-04-27}} 2. ^1 2 3 4 5 6 7 8 {{Cite web|url=https://www.ncbi.nlm.nih.gov/gene/?term=LOC105377021|title=LOC105377021 putative uncharacterized protein UNQ6490/PRO21339 [Homo sapiens (human)] - Gene - NCBI|website=www.ncbi.nlm.nih.gov|access-date=2016-02-06}} 3. ^1 2 {{Cite web|title = AceView a comprehensive annotation of human and worm genes with mRNAs or ESTsAceView.|url = https://www.ncbi.nlm.nih.gov/ieb/research/acembly/index.html|website = www.ncbi.nlm.nih.gov|access-date = 2016-02-20|first = Danielle Thierry-Mieg and Jean Thierry-Mieg, NCBI/NLM/NIH,|last = mieg@ncbi.nlm.nih.gov}} 4. ^{{Cite web|url=https://genome.ucsc.edu/cgi-bin/hgBlat?command=start|title=Human BLAT Search|website=genome.ucsc.edu|access-date=2016-05-06}} 5. ^{{Cite journal|last=Toldo|first=Luca|last2=Kindler|first2=Bjorn | name-list-format = vanc |date=2016|title=Isoelectric point determination|url=|journal=EMBL WWW Gateway to Isoelectric Point Service|doi=|pmid=|access-date=}} 6. ^1 {{cite journal | vauthors = Brendel V, Bucher P, Nourbakhsh IR, Blaisdell BE, Karlin S | title = Methods and algorithms for statistical analysis of protein sequences | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 89 | issue = 6 | pages = 2002–6 | year = 1992 | pmid = 1549558 | pmc = 48584 | doi = 10.1073/pnas.89.6.2002| url = }} 7. ^1 {{cite web | last = Brendel | first = Volker | name-list-format = vanc | date = 1992 | title = SAPS | url = http://brendelgroup.org/bioinformatics2go/SAPS-SSPA.php | publisher = Department of Mathematics, Stanford University }} 8. ^1 {{cite web | url = http://toolkit.tuebingen.mpg.de/ali2d | title = Ali2D | last = Remmert | first = Michael | name-list-format = vanc | website = toolkit.tuebingen.mpg.de | access-date = 2016-04-27}} 9. ^{{cite journal | vauthors = Ceroni A, Passerini A, Vullo A, Frasconi P | title = DISULFIND: a disulfide bonding state and cysteine connectivity prediction server | journal = Nucleic Acids Research | volume = 34 | issue = Web Server issue | pages = W177–81 | date = July 2006 | pmid = 16844986 | pmc = 1538823 | doi = 10.1093/nar/gkl266 }} 10. ^{{Cite web|url=http://zhanglab.ccmb.med.umich.edu/I-TASSER/|title=I-TASSER server for protein structure and function prediction|website=zhanglab.ccmb.med.umich.edu|access-date=2016-05-06}} 11. ^{{Cite web|url=http://myhits.isb-sib.ch/cgi-bin/motif_scan|title=Motif Scan|website=myhits.isb-sib.ch|access-date=2016-04-27}} 12. ^{{Cite web|url=http://www.cbs.dtu.dk/services/NetPhos/|title=Sequence-and structure-based prediction of eukaryotic protein phosphorylation sites|last=Blom|first=N|last2=Gammeltoft|first2=S | name-list-format = vanc |date=1999|website=www.cbs.dtu.dk|access-date=2016-04-27|last3=Brunak|first3=S}} 13. ^{{Cite web|url=http://www.cbs.dtu.dk/services/YinOYang/|title=Prediction of glycosylation sites in proteomes: from post-translational modifications to protein function| vauthors = Gupta R |website=www.cbs.dtu.dk|access-date=2016-05-04}} 14. ^{{cite journal | vauthors = Gupta R, Brunak S | title = Prediction of glycosylation across the human proteome and the correlation to protein function | journal = Pacific Symposium on Biocomputing.
