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.

Human positive cofactor 4 (PC4) mediates activator-dependent transcription by RNA polymerase II, apparently through interactions with transcriptional activators and the basal transcription machinery. We report here that PC4 function is modulated by in vivo phosphorylation. Protein-protein interaction studies and in

Our investigations of mammalian class II gene transcription resulted in identification, purification, and cloning of the corresponding cDNA of a cellular factor (p15) that mediates the effects of several distinct activators on transcription in vitro. Functional deletion analyses revealed a

Activator-dependent transcription in mammalian cells requires upstream stimulatory activity (USA)-derived cofactors in addition to those present in TFIID. A novel positive cofactor (PC4) purified from the human USA fraction effected a marked enhancement (up to 85-fold) of GAL4-AH-dependent transcription in
