Summaries for MUC2 Gene

Entrez Gene Summary for MUC2 Gene

  • This gene encodes a member of the mucin protein family. Mucins are high molecular weight glycoproteins produced by many epithelial tissues. The protein encoded by this gene is secreted and forms an insoluble mucous barrier that protects the gut lumen. The protein polymerizes into a gel of which 80% is composed of oligosaccharide side chains by weight. The protein features a central domain containing tandem repeats rich in threonine and proline that varies between 50 and 115 copies in different individuals. Downregulation of this gene has been observed in patients with Crohn disease and ulcerative colitis. [provided by RefSeq, Oct 2016]

GeneCards Summary for MUC2 Gene

MUC2 (Mucin 2, Oligomeric Mucus/Gel-Forming) is a Protein Coding gene. Diseases associated with MUC2 include Gastric Cancer and Pseudomyxoma Peritonei. Among its related pathways are O-linked glycosylation and NTHi-Induced Signaling.

UniProtKB/Swiss-Prot for MUC2 Gene

  • Coats the epithelia of the intestines, airways, and other mucus membrane-containing organs. Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. Major constituent of both the inner and outer mucus layers of the colon and may play a role in excluding bacteria from the inner mucus layer.

Post-translational modifications for MUC2 Gene

  • O-glycosylated.
  • May undergo proteolytic cleavage in the outer mucus layer of the colon, contributing to the expanded volume and loose nature of this layer which allows for bacterial colonization in contrast to the inner mucus layer which is dense and devoid of bacteria.
  • At low pH of 6 and under, undergoes autocatalytic cleavage in vitro in the N-terminal region of the fourth VWD domain. It is likely that this also occurs in vivo and is triggered by the low pH of the late secretory pathway.
  • Glycosylation at isoforms=5069, isoforms=5038, Asn5019, isoforms=4970, Asn4955, isoforms=4888, isoforms=4881, Asn4787, Asn4752, isoforms=4627, isoforms=4616, isoforms=4502, Asn4438, Asn4422, Asn4373, isoforms=4362, isoforms=4351, isoforms=4339, isoforms=1820, isoforms=1787, Asn1246, Asn1230, Asn1215, Asn1154, Asn1139, Asn894, Asn770, isoforms=670, Asn423, and Asn163
