It controls the release of Yersinia outer proteins (Yops) which help Yersinia evade the immune system. More specifically, it interacts with the bacterial protein YopN via hydrophobic residues located on the helices. FunctionThis protein domain is involved in the control of Yop release. This helps it to evade the host's immune system. Yersinia spp. do this by injecting the effector Yersinia outer proteins (Yops) into the target cell. Also involved in Yop secretion are YopN and LcrG. TyeA is also required for translocation of YopE and YopH. TyeA interacts with YopN and with YopD, a component of the translocation apparatus. This shows the complex which recognizes eukaryotic cells and controls Yop secretion is also actively involved in translocation.[1] LocalisationLike YopN, TyeA is localized at the bacterial surface. StructureThe structure of TyeA is composed of two pairs of parallel alpha-helices.[2] MechanismAssociation of TyeA with the C terminus of YopN is accompanied by conformational changes in both polypeptides that create order out of disorder: the resulting structure then serves as an impediment to type III secretion of YopN.[2] References1. ^{{cite journal |vauthors=Iriarte M, Sory MP, Boland A, Boyd AP, Mills SD, Lambermont I, etal | title=TyeA, a protein involved in control of Yop release and in translocation of Yersinia Yop effectors. | journal=EMBO J | year= 1998 | volume= 17 | issue= 7 | pages= 1907–18 | pmid=9524114 | doi=10.1093/emboj/17.7.1907 | pmc=1170537 }} {{InterPro content|IPR015144}}2. ^1 {{cite journal |vauthors=Schubot FD, Jackson MW, Penrose KJ, Cherry S, Tropea JE, Plano GV, etal | title=Three-dimensional structure of a macromolecular assembly that regulates type III secretion in Yersinia pestis. | journal=J Mol Biol | year= 2005 | volume= 346 | issue= 4 | pages= 1147–61 | pmid=15701523 | doi=10.1016/j.jmb.2004.12.036 | pmc= | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=15701523 }} 1 : Protein domains |
