|Function||Arginine methyltransferase that methylates (mono and asymmetric dimethylation) the guanidino nitrogens of arginyl residues present in proteins such as ESR1, histone H2, H3 and H4, PIAS1, HNRNPA1, HNRNPD, NFATC2IP, SUPT5H, TAF15 and EWS. Constitutes the main enzyme that mediates monomethylation and asymmetric dimethylation of histone H4 'Arg-4' (H4R3me1 and H4R3me2a, respectively), a specific tag for epigenetic transcriptional activation. Together with dimethylated PIAS1, represses STAT1 transcriptional activity, in the late phase of interferon gamma (IFN-gamma) signaling. May be involved in the regulation of TAF15 transcriptional activity, act as an activator of estrogen receptor (ER)-mediated transactivation, play a key role in neurite outgrowth and act as a negative regulator of megakaryocytic differentiation, by modulating p38 MAPK pathway. Methylates FOXO1 and retains it in the nucleus increasing its transcriptional activity. Methylates CHTOP and this methylation is critical for its 5-hydroxymethylcytosine (5hmC)-binding activity (PubMed:25284789). Methylates H4R3 in genes involved in glioblastomagenesis in a CHTOP- and/or TET1-dependent manner (PubMed:25284789).|
|Cellular Location||Nucleus. Nucleus, nucleoplasm. Cytoplasm, cytosol. Note=Mostly found in the cytoplasm. Colocalizes with CHTOP within the nucleus. Low levels detected also in the chromatin fraction (By similarity).|
|Tissue Location||Widely expressed.|

PRMT1 is a member of the Protein arginine methyltransferases (PRMTs) family that regulates mRNA processing and maturation by modulating the activity of RNA-binding proteins through methylation (1). PRMTs have been implicated in a variety of processes, including cell proliferation, signal transduction, and protein trafficking. Eleven PRMTs have been identified in humans. Except for PRMT2, 10 and 11, all PRMTs have been shown to catalyze arginine methylation, with PRMT1, 4, 5, 7, 8 and 9 have the ability to also methylate histones (2). PRMT1 appears to be a major type I enzyme in embryonic stem cells, and in wild-type cells, most substrates of the enzyme appear to be maintained in a fully methylated state (3).
