Protein arginine methylation is an important posttranslational modification in eukaryotic cells, which has been implicated in RNA processing and trafficking, receptor-mediated signaling, and transcription. PRMT4 belongs to a family of proteins that catalyzes the methylation of arginine residues. The PRMT proteins are recruited by C-terminal activation domain 2 of the SRC (steroid receptor coactivator) GRIP1, whereas p300 interacts with activation domain 1 in the C terminus. CARM1 can methylate histone H3 in vitro, and a mutation in the putative S-adenosylmethionine binding domain of CARM1 substantially reduces both methyltransferase and coactivator activities suggesting that coactivator mediated methylation of proteins in the transcription machinery may contribute to transcriptional regulation.
Applications:
Suitable for use in Western Blot. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
