Activity of PRMT1-deficient cell extracts on protein substrates. Cell extracts from PRMT1(+/+) and PRMT1(−/−) ES cells were incubated with [14C]SAM and recombinant GST-68_GRP, PABPN1, or hnRNP K (10 pmol each). Reactions were resolved on 12% SDS PAGE and methylation was detected by autoradiography.
