What is the function of this protein?
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 and may regulate its transcriptional elongation properties (By similarity).  May methylate the N-terminal region of MBD2 (By similarity).  Mono- and dimethylates arginine residues of myelin basic protein (MBP) in vitro.  May play a role in cytokine-activated transduction pathways.  Negatively regulates cyclin E1 promoter activity and cellular proliferation.  Methylates histone H2A and H4 'Arg-3' during germ cell development (By similarity).  Methylates histone H3 'Arg-8', which may repress transcription (By similarity).  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 (By similarity).  Methylates RPS10.  Attenuates EGF signaling through the MAPK1/MAPK3 pathway acting at 2 levels.  First, monomethylates EGFR; this enhances EGFR 'Tyr-1197' phosphorylation and PTPN6 recruitment, eventually leading to reduced SOS1 phosphorylation.  Second, methylates RAF1 and probably BRAF, hence destabilizing these 2 signaling proteins and reducing their catalytic activity.  Required for induction of E-selectin and VCAM-1, on the endothelial cells surface at sites of inflammation.  Methylates HOXA9.  Methylates and regulates SRGAP2 which is involved in cell migration and differentiation (By similarity).  Acts as a transcriptional corepressor in CRY1-mediated repression of the core circadian component PER1 by regulating the H4R3 dimethylation at the PER1 promoter (By similarity).  Methylates GM130/GOLGA2, regulating Golgi ribbon formation.  Methylates H4R3 in genes involved in glioblastomagenesis in a CHTOP- and/or TET1-dependent manner.  Symmetrically methylates POLR2A, a modification that allows the recruitment to POLR2A of proteins including SMN1/SMN2 and SETX.  This is required for resolving RNA-DNA hybrids created by RNA polymerase II, that form R-loop in transcription terminal regions, an important step in proper transcription termination.  Along with LYAR, binds the promoter of gamma-globin HBG1/HBG2 and represses its expression.  Symmetrically methylates NCL.  Methylates p53/TP53; methylation might possibly affect p53/TP53 target gene specificity (By similarity).  Involved in spliceosome maturation and mRNA splicing in prophase I spermatocytes through the catalysis of the symmetrical arginine dimethylation of SNRPB (small nuclear ribonucleoprotein-associated protein) and the interaction with tudor domain-containing protein TDRD6 (By similarity).
