Official Full Name
protein arginine methyltransferase 5

Overview
Arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and symmetrical dimethylarginine (sDMA), with a preference for the formation of MMA. Specifically mediates the symmetrical dimethylation of arginine residues in the small nuclear ribonucleoproteins Sm D1 (SNRPD1) and Sm D3 (SNRPD3); such methylation being required for the assembly and biogenesis of snRNP core particles. Methylates SUPT5H. Mono- and dimethylates arginine residues of myelin basic protein (MBP) in vitro. Plays a role in the assembly of snRNP core particles. May play a role in cytokine-activated transduction pathways. Negatively regulates cyclin E1 promoter activity and cellular proliferation. May regulate the SUPT5H transcriptional elongation properties. May be part of a pathway that is connected to a chloride current, possibly through cytoskeletal rearrangement. Methylates histone H2A and H4 'Arg-3' during germ cell development. Methylates histone H3 'Arg-8', which may repress transcription. Methylates the Piwi proteins (PIWIL1, PIWIL2 and PIWIL4), methylation of Piwi proteins being required for the interaction with Tudor domain-containing proteins and subsequent localization to the meiotic nuage. Methylates RPS10. -

What is prmt5 protein?
PRMT5 (Protein Arginine Methyltransferase 5) is an enzyme that participates in the process of protein arginine methylation. It specifically catalyzes the transfer of methyl groups from S-adenosylmethionine (SAM) to arginine residues in target proteins. PRMT5 is involved in various cellular processes including gene expression regulation, RNA splicing, DNA damage response, and signal transduction pathways. It plays a crucial role in the development and function of cells, and its dysregulation has been associated with several diseases, including cancer.
What is the function of prmt5 protein?
Gene expression regulation: It methylates histones and transcription factors, influencing chromatin structure and transcription.
Epigenetic gene silencing: PRMT5 mediates the formation of symmetric dimethyl arginine marks on histones involved in gene repression.
Alternative splicing: It methylates RNA-binding proteins like Sm proteins to regulate spliceosome activity and RNA splicing.
mRNA processing and transport: PRMT5 influences messenger RNA metabolism by modifying proteins of this pathway.
Cell signaling: It methylates non-histone proteins in key signaling cascades like Wnt, MAPK, PI3K-Akt etc.
Prmt5 related signaling pathway
Wnt/β-catenin pathway: PRMT5 methylates components of this pathway like adenomatous polyposis coli (APC) protein.
MAPK signaling pathway: It regulates the MAPK pathway by methylating Ras, Raf and MEK kinases.
PI3K/Akt signaling: PRMT5 methylation influences PI3K/Akt cascade involved in growth, proliferation and metabolism.
Hippo signaling pathway: Modulates the Hippo pathway by methylating key tumor suppressors like Lats2.
PRMT5 Related Diseases
Cancer: Overexpression linked to various cancers like leukemia, lung, breast, prostate cancers. Promotes oncogenesis.
Viral infections: Required for replication of certain viruses like HIV, influenza and herpes simplex viruses.
Immunodeficiency: PRMT5 deficiency impairs immune cell development and function, predisposing to infections.
Metabolic syndrome: Dysregulation associated with insulin resistance, obesity, diabetes and fatty liver disease.
Biomedical Application of PRMT5 Protein
- Cancer therapy: PRMT5 inhibitors show promise against certain hematological and solid tumors.
- Anti-viral drugs: Targeting PRMT5-virus protein interactions could yield new antiviral strategies.
- Immunomodulation: Modulating its activity may benefit immunodeficiencies and autoimmune disorders.
- Anti-fibrotic therapy: Attenuating TGF-β signaling via PRMT5 inhibition offers organ fibrosis treatment.

Fig3. S15 phosphorylation is critical for the methyltransferase activity of PRMT5. AlphaLISA assay was conducted by using biotinylated histone H4 as a PRMT5 substrate. Graph shows detection of specific methyltransferase activity of WT-PRMT5 (WT) or S15A-PRMT5 (S15A) mutant enzymes purified from HEK293 cells in the presence or absence of 10 ng/mL of IL-1β. E444D-PRMT5 (E444D) was used as an enzymatic dead mutant control. S-adenosyl methionine (SAM) was used as the methyl donor for the reaction. The data represent the means ± standard deviation (S.D.) for three independent experiments.
