PRMT5 (human)

PRMT5 an ubiquitous enzyme with protein methyltransferase activity. Methylates specific arginine residues in the transcription elongation factor SPT5, and the small nuclear ribonucleoproteins SNRPD1 and SNRPD3. Plays a role in the assembly of snRNP core particles. May play a role in cytokine-activated transduction pathways. Negatively regulates cyclin E1 promoter activity and cellular proliferation. May regulate the SPT5 transcriptional elongation properties. May be part of a pathway that is connected to a chloride current, possibly through cytoskeletal rearrangement. Component of the methylosome, a 20S complex that includes ICLN, SKB1 and WDR77. Component of a high molecular weight E2F-pocket protein complex, CERC (cyclin E1 repressor complex). Also interacts with Sm proteins, JAK2, SSTR1 and SPT5. Associates with SWI/SNF remodeling complexes containing SMARCA2 and SMARCA4. Note: This description may include information from UniProtKB.
