RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: General coactivator that functions cooperatively with TAFs
CC and mediates functional interactions between upstream activators and
CC the general transcriptional machinery. May be involved in stabilizing
CC the multiprotein transcription complex. Binds single-stranded DNA. Also
CC binds, in vitro, non-specifically to double-stranded DNA (ds DNA) (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Interacts with CSTF2 (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- PTM: Activity is controlled by protein kinases that target the
CC regulatory region. Phosphorylation inactivates both ds DNA-binding and
CC cofactor function, but does not affect binding to ssDNA (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the transcriptional coactivator PC4 family.
CC {ECO:0000305}.
