Protein arginine methyltransferase 5

(Redirected from Prmt5)

Protein arginine N-methyltransferase 5 is an enzyme that in humans is encoded by the PRMT5 gene.[5][6] PRMT5 symmetrically dimethylates H2AR3, H4R3, H3R2, and H3R8 in vivo, all of which are linked to a range of transcriptional regulatory events.[7]

PRMT5 is a highly conserved arginine methyltransferase that translocated from the cytoplasm to the nucleus at embryonic day ~E8.5, and during preimplantation development at the ~4-cell stage.[8]

Interactions

edit

Protein arginine methyltransferase 5 has been shown to interact with:

PRMT5 has been shown to interact with CLNS1A, RIOK1 and COPR5 through an interface created by a shallow groove located on the TIM barrel domain of PRMT5 and the consensus sequence GQF[D/E]DA[E/D] located in the terminal regions of the adaptor proteins.[12][16] The characterisation of the interactions occurring in the binding groove between PRMT5 and peptides derived from the adaptor proteins lead to development of protein-protein interaction (PPI) inhibitors, modulating binding between PRMT5 and the adaptor proteins.[17][18] Furthermore, Asberry and co-workers synthesised the first-in-class small molecule inhibitor of the PPI between PRMT5 and MEP50.[19] The PPI inhibitors complement a plethora of compounds directly suppressing the enzymatic activity of PRMT5.[20]
