Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001806
UniProt IDQ9UBG0
Primary gene name(s)MRC2
Synonym gene name(s)CLEC13E, ENDO180, KIAA0709, UPARAP
Protein nameC-type mannose receptor 2
Protein functionMay play a role as endocytotic lectin receptor displaying calcium-dependent lectin activity. Internalizes glycosylated ligands from the extracellular space for release in an endosomal compartment via clathrin-mediated endocytosis. May be involved in plasminogen activation system controlling the extracellular level of PLAUR/PLAU, and thus may regulate protease activity at the cell surface. May contribute to cellular uptake, remodeling and degradation of extracellular collagen matrices. May play a role during cancer progression as well as in other chronic tissue destructive diseases acting on collagen turnover. May participate in remodeling of extracellular matrix cooperating with the matrix metalloproteinases, MMPs. {ECO:0000269|PubMed:10683150, ECO:0000269|PubMed:12972549}.
