Background: TEX19

TEX19 (testis expressed sequence 19) is an 18 kDa (predicted) protein with restricted cell expression. It is expressed in spermatogonia as well as pluripotent stem cells. TEX19 has been found in both nucleus and cytoplasm. Functionally, TEX19 is proposed to guard against inappropriately activated endogenous retroviruses during meiosis, and thus prevent deleterious mutations. Human TEX19 is 164 amino acids (aa) in length. There is no identifiable structural module within the protein. There are, however, two sequences that are conserved in TEX19 from multiple species. These are an MCP domain between aa 1-58, and a VPTEL domain that spans aa 120-157. Over aa 1-164, human TEX19 shares only 53% aa identity with a highly divergent and substantially larger 42 kDa mouse TEX19.1 protein.
