The protein encoded by the TEX14 gene is necessary for intercellular bridges in germ cells, which are required for spermatogenesis. Three transcript variants encoding different isoforms have been found for this gene.
Required for spermatogenesis and male fertility. May be required for normal structure of the intercellular bridge that connects spermatocytes and spermatogonia. Has no protein kinase activity (in vitro) (By similarity).
