General annotation (Comments)

Function	Membrane-associated arginine methyltransferase that can both catalyze the formation of omega-N monomethylarginine (MMA) and asymmetrical dimethylarginine (aDMA). Able to mono- and dimethylate EWS protein; however its precise role toward EWS remains unclear as it still interacts with fully methylated EWS. Ref.5 Ref.6 Ref.7
Subunit structure	Homodimers and heterodimers with PRMT1 or PRMT2, recruiting PRMT1 to the cell membrane. Interacts with PRMT2 and FYN (via the SH3 domain). Interacts with EWS; independently of EWS methylation status. Ref.6 Ref.7
Subcellular location	Cell membrane; Lipid-anchor; Cytoplasmic side Ref.5 Ref.7.
Tissue specificity	Brain-specific. Ref.5
Domain	The SH3-binding motifs mediate the interaction with SH3 domain-containing proteins such as PRMT2 and FYN, possibly leading to displace the N-terminal domain and activate the protein. Ref.6 The N-terminal region (1-60) inhibits the enzymatic activity. Ref.6
Sequence similarities	Belongs to the protein arginine N-methyltransferase family. PRMT8 subfamily.
Biophysicochemical properties	Kinetic parameters: KM=1.3 µM for GRGGFGGRGGFRGGRGG-NH2 Ref.7
Sequence caution	The sequence AAF91390.1 differs from that shown. Reason: Erroneous initiation. The sequence BAG37987.1 differs from that shown. Reason: Frameshift at position 45.
