Functioni

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, EWS, HABP4 and SERBP1 (PubMed:16879614, PubMed:26876602). 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 RBM15, promoting ubiquitination and degradation of RBM15 (PubMed:26575292). 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).15 Publications

Subunit structurei

Homodimer (PubMed:16879614, PubMed:26876602). Homooctamer; individual homodimers associates to form a homooctamer (PubMed:26876602). Individual homodimers can associate to form a homohexamer. Heterodimer with PRMT8. Interacts with BTG1, BTG2, NFATC2IP and IFNAR1 (By similarity). Interacts with and methylates CHTOP, thereby enabling the interaction of CHTOP with the 5FMC complex (PubMed:25284789). Interacts with ILF3 and SUPT5H. Interacts with and methylates FOXO1, leading to the nuclear retention of FOXO1 and the stimulation of FOXO1 transcriptional activity. Methylation of FOXO1 is increased upon oxidative stress. Interacts with and probably methylates ATXN2L (PubMed:25748791). Component of the methylosome, a 20S complex containing at least CLNS1A/pICln, PRMT5/SKB1, WDR77/MEP50, PRMT1 and ERH (PubMed:25284789). Interacts with DHX9 (via RGG region) (PubMed:15084609).
