| Type: | Conserved_site | Name: | CCAAT-binding factor, conserved site |
| Description: | The CCAAT-binding factor (CBFB/NF-YA) is a mammalian transcription factor that binds to a CCAAT motif in the promoters of a wide variety of genes, including type I collagen and albumin []. The factor is a heteromeric complex of A and B subunits, both of which are required for DNA-binding []. The subunits can interact in the absence of DNA-binding, conserved regions in each being important in mediating this interaction. The B subunit contains a region of similarity with the yeast protein HAP2 []. For the B subunit it has been suggested that the N-terminal portion of the conserved region is involved in subunit interaction and the C-terminal region involved in DNA-binding []. | Short Name: | CCAAT-binding_factor_CS |
