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 properties

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

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.

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

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

An evolving hypothesis postulates that melanomas may arise through 'nevus-associated' and 'chronic sun exposure' pathways. We explored this hypothesis by examining associations between nevus-associated loci and melanoma risk across strata of body site and histological subtype. We genotyped 1028 invasive
