Summary: Enables aspartic-type peptidase activity and glutamic-type peptidase activity. Involved in several processes, including negative regulation of binding activity of sperm to zona pellucida; positive regulation of protein processing; and prevention of polyspermy. Located in cortical granule and plasma membrane. Is expressed in early conceptus and oocyte. Orthologous to human ASTL (astacin like metalloendopeptidase).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_766127.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate 5' terminal exon, and it thus differs in its 5' UTR and initiates translation at a downstream in-frame start codon, compared to variant 1. The encoded isoform (b) is shorter at the N-terminus, compared to isoform a.
