Proposed be a specific endogenous inhibitor of PCSK1. ProSAAS and Big PEN-LEN, both containing the C-terminal inhibitory domain, but not the further processed peptides reduce PCSK1 activity in the endoplasmic reticulum and Golgi. It reduces the activity of the 84 kDa form but not the autocatalytically derived 66 kDa form of PCSK1. Subsequent processing of proSAAS may eliminate the inhibition. Slows down convertase-mediated processing of proopiomelanocortin and proenkephalin. May control the intracellular timing of PCSK1 rather than its total level of activity. The function of the processed secreted peptides is not known (By similarity). {ECO:0000250}. |ProSAAS| |response to dietary excess| |peptide hormone processing| |endopeptidase inhibitor activity| |response to cold| |secretory granule| |serine-type endopeptidase inhibitor activity| |neuropeptide signaling pathway| |protein processing| |trans-Golgi network| |response to temperature stimulus| |hormone metabolic process| |protein maturation| |negative regulation of endopeptidase activity| |negative regulation of peptidase activity| |signaling receptor binding| |negative regulation of proteolysis| |regulation of endopeptidase activity| |regulation of peptidase activity| |negative regulation of hydrolase activity| |response to nutrient levels| |peptide metabolic process| |response to extracellular stimulus| |regulation of hormone levels| |regulation of proteolysis| |cellular amide metabolic process| |negative regulation of catalytic activity| |negative regulation of cellular protein metabolic process| |negative regulation of protein metabolic process| |negative regulation of molecular function| |response to abiotic stimulus| |proteolysis| |regulation of hydrolase activity| |G protein-coupled receptor signaling pathway| |extracellular space| |gene expression| \\ === CRISPR Data === No hits were found.
