Background CA125 is a tumor antigen widely used in monitoring ovarian cancer. Using a rabbit polyclonal antibody produced to purified CA125 antigen to screen cells from an ovarian cancer cell (OVCAR-3) cDNA library in E. coli, Yin and Lloyd (2001) cloned a long partial cDNA, which they designated MUC16, corresponding to the CA125 antigen. The deduced 1,890-amino acid protein contains characteristic features of a mucin-type molecule, including a high serine, threonine, and proline content in an N-terminal region of 9 partially conserved tandem repeats and a C-terminal region nontandem repeat sequence containing a possible transmembrane region and a potential tyrosine phosphorylation site. MUC16 also has a high leucine content. Northern blot analysis showed that the level of MUC16 mRNA correlated with the expression of CA125 in a panel of cell lines. [Provide by OMIN]
Function Thought to provide a protective, lubricating barrier against particles and infectious agents at mucosal surfaces. [UniProt]
Research Area Cancer antibody; Controls and Markers antibody; Signaling Transduction antibody
PTM Heavily O-glycosylated; expresses both type 1 and type 2 core glycans.
Heavily N-glycosylated; expresses primarily high mannose and complex bisecting type N-linked glycans.
May be phosphorylated. Phosphorylation of the intracellular C-terminal domain may induce proteolytic cleavage and the liberation of the extracellular domain into the extracellular space.
May contain numerous disulfide bridges. Association of several molecules of the secreted form may occur through interchain disulfide bridges providing an extraordinarily large gel-like matrix in the extracellular space or in the lumen of secretory ducts.
