GENE INFORMATION
Gene name	SPINT1 (HGNC Symbol)
Synonyms	HAI, MANSC2
Description	Serine peptidase inhibitor, Kunitz type 1 (HGNC Symbol)
Entrez gene summary	The protein encoded by this gene is a member of the Kunitz family of serine protease inhibitors. The protein is a potent inhibitor specific for HGF activator and is thought to be involved in the regulation of the proteolytic activation of HGF in injured tissues. Alternative splicing results in multiple variants encoding different isoforms. [provided by RefSeq, Jul 2008]
