ASP — Solanum tuberosum

Summary

PGSC0003DMG400010137 (ASP, also known as INH or StASP) on potato chromosome 3 encodes a Kunitz-type protease inhibitor with aspartic-type, cysteine-type and serine-type endopeptidase inhibitor activities. The gene is associated with polysaccharide metabolism, starch breakdown, starch metabolism, sucrose metabolism, protein breakdown, proteolysis, nucleotide anabolism, RNA splicing, signal transduction, defense response, cell death, NO storage and secretion. The product localises to the vacuole. Associations with soluble protein, sucrose, sugar and protein content have been noted. Studies of related genes in other species link the family to starch yield, starch content, flavonoid content and stigma exsertion.
