Supplementary information

ZP2 also known as zona pellucida glycoprotein 2 is a structural protein critical to the protective coat surrounding oocytes called the zona pellucida. The protein is approximately 68 kDa in mass. ZP2 is highly expressed in the ovary. This glycoprotein specifically contributes to the matrix of the zona pellucida with other related proteins forming a structure that enables various reproductive events like sperm binding and prevention of polyspermy.
Biological function summary

ZP2 interacts with other zona pellucida proteins particularly ZP1 and ZP3 to form the zona pellucida matrix. This matrix allows the binding of sperm to the oocyte facilitating fertilization. The stability and integrity of this structure determine reproductive success and embryo development. ZP2 undergoes proteolytic cleavage during the fertilization process which is an important event for proper egg-sperm interaction.

Pathways

ZP2 forms an integral part of the fertilization pathway where it directly interacts with proteins ZP1 and ZP3. These proteins create a framework critical for sperm recognition and binding. Once ZP2 undergoes cleavage it assists in the progression of the acrosome reaction an important biological pathway for sperm penetration of the zona pellucida. The interactions and modifications of ZP2 within these pathways highlight the importance of precise regulation in reproduction.

Mutations or abnormalities in ZP2 are linked to reproductive conditions such as infertility. These changes can lead to disrupted zona pellucida integrity which affects sperm binding and fertilization ability. Additionally abnormalities in ZP2 relate to oocyte maturation defects impacting reproductive health. The protein also shows interplay with ZP3 in these conditions underlining its collaborative role in maintaining fertility.

General info

Function

Component of the zona pellucida, an extracellular matrix surrounding oocytes which mediates sperm binding, induction of the acrosome reaction and prevents post-fertilization polyspermy (PubMed : 29895852). The zona pellucida is composed of 3 to 4 glycoproteins, ZP1, ZP2, ZP3, and ZP4. ZP2 may act as a secondary sperm receptor (PubMed : 29895852).

Sequence similarities

Belongs to the ZP domain family. ZPA subfamily.

Post-translational modifications

Proteolytically cleaved before the transmembrane segment to yield the secreted ectodomain incorporated in the zona pellucida.. Proteolytically cleaved in the N-terminal part by the metalloendopeptidase ASTL exocytosed from cortical granules after fertilization, yielding a N-terminal peptide of about 30 kDa which remains covalently attached to the C-terminal peptide via disulfide bond(s). This cleavage may play an important role in the post-fertilization block to polyspermy. Additional proteolytically cleavage of the N-terminal peptide of 30 kDa occurs in one-cell and two-cell embryos.. N-glycosylated.. O-glycosylated; contains sulfate-substituted glycans.
