RT   "N-terminal sequence of Binder of Sperm 1 (BSP1/PDC-109) homologue purified
RT   from the seminal plasma of Bos indicus bulls.";
RL   Submitted (APR-2012) to UniProtKB.
CC   -!- FUNCTION: Could enhance the fertilizing capacity of bull spermatozoa
CC       upon interaction with heparin-like glycosaminoglycans present in the
CC       female genital tract. Exhibits both simulatory and inhibitory actions
CC       on the release of pituitary gonadotropins (By similarity). Binds to
CC       heparin and gelatin. {ECO:0000250|UniProtKB:P02784, ECO:0000269|Ref.1}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P02784}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.1}.
CC   -!- SIMILARITY: Belongs to the seminal plasma protein family.
CC       {ECO:0000255}.
