TAF1C

Template:Short description Template:Infobox gene TATA box-binding protein-associated factor RNA polymerase I subunit C is an enzyme that in humans is encoded by the TAF1C gene.

Function

Initiation of transcription by RNA polymerase I requires the formation of a complex composed of the TATA-binding protein (TBP) and three TBP-associated factors (TAFs) specific for RNA polymerase I. This complex, known as SL1, binds to the core promoter of ribosomal RNA genes to position the polymerase properly and acts as a channel for regulatory signals. This gene encodes the largest SL1-specific TAF. Two transcripts encoding different isoforms have been identified.

Interactions

TAF1C has been shown to interact with UBTF.
