PC4, serine mutations human

产品说明

生化/生理作用

Human PC4 is a non-TAF transcription coactivator that mediates activator-dependent transcription by RNA polymerase II in vitro through most tested activators. The function of PC4 is through interactions with transcriptional activators and the basal transcription machinery. It is negatively regulated by casein kinase II phosphorylation both in vitro and in vivo. PC4 strongly binds single stranded DNA and the region essential for the single stranded DNA binding activity was mapped around residue 77. A single amino acid change at position 77 (F to P) abolishes both ds- and ss-DNA binding activity.
