NCIt synonyms : Soluble Mesothelin Related Protein; SMR; SMRP; Megakaryocyte Potentiating Factor; OV569 Antigen; MPF; Soluble MPF/Mesothelin-Related Protein; Soluble MPF Mesothelin Related Protein; Soluble Mesothelin/MPF-Related Protein; Soluble MPF/Mesothelin Related Protein;
NCIt definition : Megakaryocyte-potentiating factor (250 aa, 27 kDa) is encoded by the human MSLN gene.
This protein plays a role in megakaryocyte colony formation.;
NCIt note : An antibody that reacts with ovarian cancers and mesotheliomas was used to isolate
a cell surface antigen named mesothelin. Although the function of mesothelin is unknown,
it may play a role in cellular adhesion and is present on mesothelium, mesotheliomas,
and ovarian cancers. Three transcript variants have been described for this gene and
their protein products were initially named megakaryocyte potentiating factor (MPF),
mesothelin, and the soluble member(s) of the mesothelin/MPF family. The protein isoform
named MPF is a cytokine with megakaryocyte potentiating activity. The soluble member
encoded by the third splice variant is detected in ovarian carcinoma; the full length
sequence of the third variant has not been described. (LocusLink);
