Testis-expressed Gene 14 (TEX14)

Description: During gametogenesis, male germ cells form a unique structure called the intercellular bridge (IB). It is thought the IB plays a role in germ cell communication, synchronization, and chromosome dosage compensation in haploid cells. TEX14 is critical in the formation of the IB; absence of TEX14 disrupts IB formation and causes sterility.
