Function

[ANM1_RAT] 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.^[1] ^[2] ^[3]

Publication Abstract from PubMed

PRMT1 is the predominant type I protein arginine methyltransferase in mammals and highly conserved among all eukaryotes. It is essential for early postimplantation development in mouse. Here we describe the crystal structure of rat PRMT1 in complex with the reaction product AdoHcy and a 19 residue substrate peptide containing three arginines. The results reveal a two-domain structure-an AdoMet binding domain and a barrel-like domain-with the active site pocket located between the two domains. Mutagenesis studies confirmed that two active site glutamates are essential for enzymatic activity, and that dimerization of PRMT1 is essential for AdoMet binding. Three peptide binding channels are identified: two are between the two domains, and the third is on the surface perpendicular to the strands forming the beta barrel.
