Rabbit Anti-IAV NME8 Polyclonal antibody for WB, ELISA. Probably required during the final stages of sperm tail maturation in the testis and/or epididymis, where extensive disulfide bonding of fibrous sheath (FS) proteins occurs. May be involved in the reduction of disulfide bonds within the sperm FS components. In vitro, it has neither NDP kinase nor reducing activity on disulfide bonds. TXNDC3 encodes a group II thioredoxin protein, composed of a thioredoxin domain and three NDP kinase domains, with testis specific expression.
