CC -!- FUNCTION: Serine protease inhibitor which exhibits anti-trypsin
CC activity (PubMed:3428272, PubMed:14645103, PubMed:22228629). In the
CC pancreas, protects against trypsin-catalyzed premature activation of
CC zymogens (PubMed:16083722). {ECO:0000269|PubMed:14645103,
CC ECO:0000269|PubMed:16083722, ECO:0000269|PubMed:22228629,
CC ECO:0000269|PubMed:3428272}.
CC -!- FUNCTION: In the male reproductive tract, binds to sperm heads where it
CC modulates sperm capacitance by inhibiting calcium uptake and nitrogen
CC oxide (NO) production (PubMed:9828198, PubMed:14645103,
CC PubMed:16083722, PubMed:22228629). {ECO:0000269|PubMed:14645103,

CC ECO:0000269|PubMed:9828198}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:1929395}.
CC -!- TISSUE SPECIFICITY: In the genital tract, expressed only in male
CC accessory glands including seminal vesicle, coagulating gland and
CC prostate. {ECO:0000269|PubMed:9828198}.
CC -!- DEVELOPMENTAL STAGE: In the seminal vesicle, not expressed during
CC prepubertal stages; expression coincides with maturation.
CC {ECO:0000269|PubMed:9828198}.
CC -!- INDUCTION: By androgens in adult male sex accessory glands. Expressed
CC constitutively in pancreas. {ECO:0000269|PubMed:3428272}.
CC -!- DISRUPTION PHENOTYPE: Lethal with no survival past two weeks of age.
CC Animals are small and show severe, progressive degeneration of
CC pancreatic tissue associated with autophagic cell death.
CC {ECO:0000269|PubMed:16083722}.
