ZP1 Rabbit Polyclonal Antibody

The zona pellucida is an extracellular matrix that surrounds the oocyte and early embryo. It is composed primarily of three or four glycoproteins with various functions during fertilization and preimplantation development. The protein encoded by this gene ensures the structural integrity of the zona pellucida. Mutations in this gene are a cause of oocyte maturation defect and infertility. [provided by RefSeq, May 2014], domain:The ZP domain is involved in the polymerization of the ZP proteins to form the zona pellucida., function:The mammalian zona pellucida, which mediates species-specific sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy, is composed of three to four glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP1 ensures the structural integrity of the zona pellucida., PTM:O-glycosylated., PTM:Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida., similarity:Belongs to the ZP domain family. ZPB subfamily., similarity:Contains 1 P-type (trefoil) domain., similarity:Contains 1 ZP domain., subunit:Polymers of ZP2 and ZP3 organized into long filaments cross-linked by ZP1 homodimers., tissue specificity:Oocytes.
