Summaries for PCSK1 Gene

Entrez Gene Summary for PCSK1 Gene

  • This gene encodes a member of the subtilisin-like proprotein convertase family, which includes proteases that process protein and peptide precursors trafficking through regulated or constitutive branches of the secretory pathway. The encoded protein undergoes an initial autocatalytic processing event in the ER to generate a heterodimer which exits the ER and sorts to subcellular compartments where a second autocatalytic even takes place and the catalytic activity is acquired. The protease is packaged into and activated in dense core secretory granules and expressed in the neuroendocrine system and brain. This gene encodes one of the seven basic amino acid-specific members which cleave their substrates at single or paired basic residues. It functions in the proteolytic activation of polypeptide hormones and neuropeptides precursors. Mutations in this gene have been associated with susceptibility to obesity and proprotein convertase 1/3 deficiency. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene [provided by RefSeq, Jan 2014]

GeneCards Summary for PCSK1 Gene

PCSK1 (Proprotein Convertase Subtilisin/Kexin Type 1) is a Protein Coding gene. Diseases associated with PCSK1 include obesity with impaired prohormone processing and obesity bmiq12. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Neuroscience. GO annotations related to this gene include serine-type endopeptidase activity. An important paralog of this gene is FURIN.

UniProtKB/Swiss-Prot for PCSK1 Gene

  • Involved in the processing of hormone and other protein precursors at sites comprised of pairs of basic amino acid residues. Substrates include POMC, renin, enkephalin, dynorphin, somatostatin and insulin
