CC -!- FUNCTION: [Acrosin-binding protein, mature form]: Acrosomal protein
CC that maintains proacrosin (pro-ACR) as an enzymatically inactive
CC zymogen in the acrosome. Involved also in the acrosome formation.
CC {ECO:0000250|UniProtKB:Q3V140}.
CC -!- SUBUNIT: [Acrosin-binding protein, mature form]: Binds proacrosin (pro-
CC ACR). Does not bind the mature form of ACR.
CC {ECO:0000250|UniProtKB:Q29016}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:Q29016}.
CC Cytoplasmic vesicle, secretory vesicle, acrosome
CC {ECO:0000250|UniProtKB:Q29016, ECO:0000250|UniProtKB:Q3V140}.
CC -!- TISSUE SPECIFICITY: Expression restricted to testis in normal tissue.
CC Expressed in a wide spectrum of cancers, including bladder, breast,
CC liver, lung and colon cancers. {ECO:0000269|PubMed:11248070}.
CC -!- PTM: Phosphorylated on Tyr residues in capacitated sperm.
CC {ECO:0000250|UniProtKB:Q29016}.
CC -!- PTM: The N-terminus is blocked. {ECO:0000250|UniProtKB:Q29016}.
CC -!- PTM: Synthesized as a 60-kDa precursor, the 32-kDa mature form is post-
CC translationally produced by the removal of the N-terminal half of the
CC precursor during sperm maturation in the testis and/or epididymis.
CC {ECO:0000250|UniProtKB:Q29016}.
