This gene encodes a member of the protein arginine N-methyltransferase (PRMT) family. Post-translational modification of target proteins by PRMTs plays an important regulatory role in many biological processes, whereby PRMTs methylate arginine residues by transferring methyl groups from S-adenosyl-L-methionine to terminal guanidino nitrogen atoms. The encoded protein is a type I PRMT and is responsible for the majority of cellular arginine methylation activity. Increased expression of this gene may play a role in many types of cancer. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 5.

Interaction

Homodimer (PubMed:16879614, 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). Interacts (via N-terminus) with HABP4 (PubMed:16879614). Interacts with MAP3K5/ASK1; the interaction results in MAP3K5 methylation by PRMT1 which inhibits MAP3K5 activation (PubMed:22095282). Interacts with TRIM48; the interaction results in ubiquitination of PRMT1 by TRIM48, leading to PRMT1 proteasomal degradation and activation of MAP3K5 (PubMed:29186683).
