PRMT5 (protein arginine methyltransferase 5) belongs to the family of protein methyltransferases. It is a human homologue of Schizosaccaromyces pombe Skb1 (Shk1 kinase-binding protein 1), and Saccharomyces cerevisiae HSL7 (histone synthetic lethal 7) proteins. This gene is localized to the chromosome 14q11.2-21. It contains the motif characteristic of protein arginine methyltransferase (PRMT) family, which are S-adenosyl-L-methionine-dependent. This protein is a type II arginine methyltransferase. It is predominantly expressed in the cytoplasm.

Application: Anti-PRMT5 antibody is suitable for immunoprecipitation and ChIP (chromatin immunoprecipitation).Anti-PRMT5 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: PRMT5 (protein arginine methyltransferase 5) forms monomethylarginine or symmetrical dimethylarginine (MMA/sDMA) by methylating isolated arginine residues or arginine residues found in glycine- and arginine-rich (GAR) motifs. As it forms a part of various protein complexes, it plays essential roles in multiple cellular process. It regulates chromatin remodeling, leading to either gene activation or repression. Cell proliferation and survival is regulated by PRMT5, through extracellular signal-regulated kinase (ERK) pathway. It methylates CRAF (c-Rapidly Accelerated Fibrosarcoma) and BRAF (b-Rapidly Accelerated Fibrosarcoma), which in turn phosphorylate ERK protein. It methylates ribosomal protein S10 (RPS10) at the Arg (158) and Arg (160) residues. RPS10, in turn regulates the assembly of ribosomes, cell proliferation and protein synthesis. Therefore, PRMT5 is involved in tumorigenesis by regulating cell proliferation. PRMT5 is also associated with inflammation and related diseases, such as atherosclerosis, by regulating HOXA9, which has a pro-inflammatory function.
