– CA9 is a member of the carbonic anhydrases’ family, that is often expressed in cancer cells under hypoxic condition. CA9 expression potentially contributes to the regulation of cancer cell differentiation and mediates tumour-associated genes and signalling pathways, including apoptosis, hypoxia, G2M checkpoint, PI3K/AKR/mTOR signalling and TGF-beta signalling pathways. CA9/Carbonic Anhydrase IX Protein, Cynomolgus, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 41.03 kDa and the accession number is A0A2K5VQG9.
