Small nuclear RNA activating complex, polypeptide 2, 45kDa
Gene Summary
SNAPc is involved in transcription by two types of polymerases; it is required for transcription of both the RNA polymerase II and III small-nuclear RNA genes and binds specifically to the proximal sequence element PSE, a non-TATA-box basal promoter element common to these two types of genes. In addition, SNAPc is composed of at least three TAFs, SNAP43, SNAP45 and SNAP50.
