General annotation (Comments)

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. Ref.9 Ref.10 Ref.11 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19
Catalytic activity	S-adenosyl-L-methionine + arginine-[histone] = S-adenosyl-L-homocysteine + N(omega)-methyl-arginine-[histone]. Ref.9 Ref.10 Ref.16
Enzyme regulation	By BTG1, BTG2 and ILF3.
Subunit structure	Homodimer and heterodimer with PRMT8. The dimer can then associate to form a homohexamer. Interacts with ILF3, BTG1, BTG2, SUPT5H and interferon-alpha/beta receptor 1. Interacts with NFATC2IP By similarity. Ref.7 Ref.8 Ref.11 Ref.15
Subcellular location	Nucleus. Cytoplasm › cytosol By similarity Ref.18.
Tissue specificity	Widely expressed. Ref.3
Sequence similarities	Belongs to the protein arginine N-methyltransferase family.
Biophysicochemical properties	Kinetic parameters: KM=1 µM for AdoMet Ref.16 KM=4.2 µM for H4 Vmax=1.2 nmol/min/mg enzyme toward AdoMet Vmax=1.24 nmol/min/mg enzyme toward H4
