Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Major glycoprotein component of a variety of mucus gels. Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. May be involved in ligand binding and intracellular signaling.SUBCELLULAR LOCATION Additional isoforms seem to exist.TISSUE SPECIFICITY Broad specificity; small intestine, colon, colonic tumors, heart, liver, thymus, prostate, pancreas and gall bladder.PTM Highly O-glycosylated and probably also N-glycosylated.MISCELLANEOUS May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.SEQUENCE CAUTION This sequence is incomplete at 5' and 3' ends and extensively differs from that shown.SEQUENCE CAUTION This sequence is incomplete at 5' and 3' ends and extensively differs from that shown.
