Protein arginine methyltransferase 1 (PRMT1) is a key player in the dynamic regulation of arginine methylation. Its dysregulation and aberrant expression are implicated in various pathological conditions, and a plethora of evidence suggests that PRMT1 inhibition is of significant therapeutic value.PRMT1 is the most highly expressed of the protein arginine methyltransferases, enzymes responsible for methylation of arginine motifs on histone and nonhistone proteins. PRMT1 regulates signal transduction and transcriptional activity that affect multiple signal pathways crucial in craniofacial development, such as the BMP, TGFbeta, and WNT pathways.
