{{Infobox_gene}}Midline-1 is a protein found in humans that is encoded by the MID1 gene.[1][2][3] Function The protein encoded by this gene is a member of the tripartite motif (TRIM) family, also known as the 'RING-B box-coiled coil' (RBCC) subgroup of RING finger proteins. The TRIM motif includes three zinc-binding domains, a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. This protein forms homodimers which associate with microtubules in the cytoplasm. The protein is likely involved in the formation of multiprotein structures acting as anchor points to microtubules. Mutations in this gene have been associated with the X-linked form of Opitz syndrome, which is characterized by midline abnormalities such as cleft lip, laryngeal cleft, heart defects, hypospadias, and agenesis of the corpus callosum. This gene was also the first example of a gene subject to X inactivation in human while escaping it in mouse. Several different transcript variants are generated by alternate splicing; however, the full length nature of two variants has not been determined.[3] Interactions MID1 has been shown to interact with MID2.[4][5] References 1. ^{{cite journal | vauthors = Quaderi NA, Schweiger S, Gaudenz K, Franco B, Rugarli EI, Berger W, Feldman GJ, Volta M, Andolfi G, Gilgenkrantz S, Marion RW, Hennekam RC, Opitz JM, Muenke M, Ropers HH, Ballabio A | title = Opitz G/BBB syndrome, a defect of midline development, is due to mutations in a new RING finger gene on Xp22 | journal = Nat Genet | volume = 17 | issue = 3 | pages = 285–91 | date = Dec 1997 | pmid = 9354791 | pmc = | doi = 10.1038/ng1197-285 }}
