應用

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 [1]. 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 [2].

生化/生理作用

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 [1][2].

物理性質

N-terminal GST-tagged 57 kDa protein containing amino acids 2-end.

Purine nucleoside metabolism in the archaeon Pyrococcus furiosus is catalyzed by purine nucleoside phosphorylase (PfPNP) and 5'-deoxy-5'-methylthioadenosine phosphorylase (PfMTAP). These enzymes, characterized by 50% amino acid sequence identity, show non-common features of thermophilicity and thermostability and are stabilized by intramolecular

Diaphyseal medullary stenosis with malignant fibrous histiocytoma (DMS-MFH) is an autosomal-dominant syndrome characterized by bone dysplasia, myopathy, and bone cancer. We previously mapped the DMS-MFH tumor-suppressing-gene locus to chromosomal region 9p21-22 but failed to identify mutations in known genes in

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
