ASP — Solanum tuberosum

Summary

PGSC0003DMG400010143, designated ASP (STKTI) on potato chromosome 3, encodes a Kunitz-type protease inhibitor family protein with Kunitz_inhibitor_STI-like superfamily and Kunitz_legume domains. The product possesses both cysteine-type and serine-type endopeptidase inhibitor activities. This gene is associated with defense response, cell death, proteolysis, protein breakdown, polysaccharide metabolism, nucleotide anabolism, primary metabolism, NO storage, and sensitization. It is linked to vacuolar localization. Associations with starch yield, starch content, sugar content, soluble protein content, and protein content have been recorded. Studies of related genes in other species connect the family to stigma exsertion, flavonoid content, and sucrose content.
