GeneCards Summary for MUC5AC Gene

MUC5AC (Mucin 5AC, Oligomeric Mucus/Gel-Forming) is a Protein Coding gene. Diseases associated with MUC5AC include anal canal adenocarcinoma and pancreatic mucinous cystadenoma. Among its related pathways are Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein and Biosynthesis of the N-glycan precursor (dolichol lipid-linked oligosaccharide, LLO) and transfer to a nascent protein. GO annotations related to this gene include extracellular matrix structural constituent. An important paralog of this gene is OTOGL.

Post-translational modifications for MUC5AC Gene

  • C-, O- and N-glycosylated. O-glycosylated on the Thr-/Ser-rich tandem repeats. C-mannosylation in the Cys-rich subdomains may be required for proper folding of these regions and for export from the endoplasmic reticulum during biosynthesis.
  • Proteolytic cleavage in the C-terminal is initiated early in the secretory pathway and does not involve a serine protease. The extent of cleavage is increased in the acidic parts of the secretory pathway. Cleavage generates a reactive group which could link the protein to a primary amide.
  • Glycosylation at Asn205, Asn258, Asn415, Asn524, Asn1308, Trp1389, Trp1584, Trp1749, Trp1957, Trp2122, Trp2652, Trp2950, Asn3198, Trp3383, Trp4009, Asn4245, Asn4318, Asn4433, Asn4469, Asn4612, Asn4723, Asn4753, Asn4762, Asn4831, Asn4904, and Asn4967
