-  Comments and Description Text from UniProtKB
  ID: MSLN_HUMAN
DESCRIPTION: RecName: Full=Mesothelin; AltName: Full=CAK1 antigen; AltName: Full=Pre-pro-megakaryocyte-potentiating factor; Contains: RecName: Full=Megakaryocyte-potentiating factor; Short=MPF; Contains: RecName: Full=Mesothelin, cleaved form; Flags: Precursor;
FUNCTION: Membrane-anchored forms may play a role in cellular adhesion.
FUNCTION: Megakaryocyte-potentiating factor (MPF) potentiates megakaryocyte colony formation in vitro.
SUBUNIT: Interacts with MUC16.
SUBCELLULAR LOCATION: Cell membrane; Lipid-anchor, GPI-anchor. Golgi apparatus.
SUBCELLULAR LOCATION: Megakaryocyte-potentiating factor: Secreted.
SUBCELLULAR LOCATION: Isoform 3: Secreted.
TISSUE SPECIFICITY: Expressed in lung. Expressed at low levels in heart, placenta and kidney. Expressed in mesothelial cells. Highly expressed in mesotheliomas, ovarian cancers, and some squamous cell carcinomas (at protein level).
PTM: Both MPF and the cleaved form of mesothelin are N- glycosylated.
PTM: Proteolytically cleaved by a furin-like convertase to generate megakaryocyte-potentiating factor (MPF), and the cleaved form of mesothelin.
DISEASE: Note=Antibodies against MSLN are detected in patients with mesothelioma and ovarian cancer.
SIMILARITY: Belongs to the mesothelin family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
