General description
N-terminal GST-tagged 57 kDa protein containing amino acids 2-end.
Application
S-methyl-5′-thioadenosine phosphorylase human (MTAP) is an enzyme used in cancer research that is deficient in many types of cancer. Decreased MTAP expression may be used as a potential indicator of disease progression of gastrointestinal stromal tumors . MTAP may be a used to develop potential therapeutic strategies for hepatocellular carcinoma (HCC) since MTAP inactivation has been linked to HCC development and invasiveness .
Biochem/physiol Actions
MTAP expression is crucial for the catabolism of methylthioadenosine, which is a by-product of polyamine biosynthesis in the methionine salvage pathway. Protein expression is decreased by homozygous deletion and promoter hypermethylation .
Physical form
Supplied as a solution in 25 mM Tris-HCl, pH 8.0,100 mM NaCl, 0.05% Tween®-20, 10% glycerol,and 3 mM DTT.

Chronic inflammation is an underlying risk factor for colon cancer. Tumor necrosis factor alpha (TNF-α) plays a critical role in the development of inflammation-induced colon cancer in a mouse model. S-adenosylmethionine (SAMe) and its metabolite methylthioadenosine (MTA) can inhibit lipopolysaccharide-induced

Malignant pleural mesothelioma (MPM) often causes diagnostic difficulties for pathologists. We assessed whether loss of methylthioadenosine phosphorylase (MTAP), a key enzyme in the intracellular recycling of adenosine triphosphate (ATP) often deleted in MPM, could be detected with immunohistochemistry (IHC) and

Chromosome 9 is frequently deleted in high-risk gastrointestinal stromal tumors (GISTs), whereas its specific tumor suppressor genes (TSGs) are less understood. We did an integrative study of MTAP gene at 9p21 to analyze its implication in GISTs. To search TSGs
