    EMSA

  • Purity> 95 % SDS-PAGE.
    ab81957 is purified by conventional chromatography.
  • FormLiquid
  • Additional notes


    Wild-type PC4, but not the kinase inhibitory-deficient mutant of PC4 (serine mutations), represses specific transcription in vivo.

  • FunctionGeneral coactivator that functions cooperatively with TAFs and mediates functional interactions between upstream activators and the general transcriptional machinery. May be involved in stabilizing the multiprotein transcription complex. Binds single-stranded DNA. Also binds, in vitro, non-specifically to double-stranded DNA (ds DNA).
  • Sequence similaritiesBelongs to the transcriptional coactivator PC4 family.
  • Post-translational
    modifications
    Activity is controlled by protein kinases that target the regulatory region. Phosphorylation inactivates both ds DNA-binding and cofactor function, but does not affect binding to ssDNA. Seems to be phosphorylated in vivo by CK2 in at least 7 sites in the N-terminal Ser-rich region.
  • Cellular localizationNucleus.
  • Information by UniProt
