Background

Testis-expressed protein 19.1 (TEX19.1; also Tex19a and Tex19) is a 40 kDa pluripotent stem cell molecule. Mouse TEX19.1 is 351 amino acids (aa) in length.  The first conserved domain is localized on the N-terminal boundary of the protein and is 58 residues long.  It is known as the MCP domain, and begins with an invariant MCPPVS motif. The second conserved domain, known as the VPTEL domain, begins with an invariant VPTEL motif and is 38 amino acids long. Mouse TEX19.1 shares 70% and 24% aa identity with rat and human Tex19.1, respectively. The protein is restricted to mammals and is expressed in testis, placenta, and ovary.  It is expressed in early embryo and is later limited to the germ line. Tex19.1 has been shown to present in the cytoplasm of spermatogonia and early spermatocytes in adult mouse testes (1). The precise function of TEX19.1 is still unknown, but it is thought to be a new transcription factor regulating target genes responsible for pluripotency or it has a role in controlling the chromatin architecture of the pluripotent nucleus.
