General description

Testis-expressed protein 19.1 (UniProt: Q99MV2; also known as mTex19.1, Testis-expressed protein 19A) is encoded by the Tex19.1 (also known as Tex19, Tex19a) gene (Gene ID: 73679) in murine species. Tex19.1 resides in the germline to repress transposable genetic elements and maintain genomic stability. It is expressed in testis, placenta, ovary, and in pluripotent stem cells. In testis its expression is highest in mitotic spermatogonia and decreases as spermatocytes progress through meiosis. Tex19.1 expression is reported to be down-regulated by Deleted in azoospermia-like (DAZL) protein, which binds to 3′UTR of Tex19.1 mRNAs and repress its translation. Tex19.1 is required during spermatogenesis and placenta development where it participates in the repression of retrotransposable elements and prevents their mobilization. Tex19.1, along with its paralog, Tex19.2, is shown to collaborate with the Piwi-interacting RNA (piRNA) pathway, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins. Embryos with mutations in Tex19.1 gene exhibit intra-uterine growth retardation and have small placentas due to a reduction in the number of spongiotrophoblast, glycogen trophoblast and sinusoidal trophoblast giant cells. Loss of Tex19.1 is shown to cause growth defect and early post-natal lethality. Male animals with deficiency of both Tex19.1 and Tex19.2 display impaired spermatogenesis, small testes, and are infertility.
