background:
CA150 is a nuclear protein that regulates transcriptional elongation and pre-mRNA splicing. It interacts with the hyperphosphorylated SLCterminal domain of RNA polymerase II via multiple FF domains, and with the pre-mRNA splicing factor SF1 via a WW domain.
Function:
Transcription factor that binds RNA polymerase II and inhibits the elongation of transcripts from target promoters. Regulates transcription elongation in a TATA box-dependent manner. Necessary for TAT-dependent activation of the human immunodeficiency virus type 1 (HISLV1) promoter.
Subunit:
Binds formin (By similarity). Binds RNA polymerase II, HD and SF1.
Subcellular Location:
Nucleus.
Tissue Specificity:
Detected in brain neurons.
Similarity:
Contains 6 FF domains.
Database links:
UniProtKB/Swiss-Prot: O14776.2
