 184-258 1.19e-43

RFX DNA-binding domain; RFX is a regulatory factor which binds to the X box of MHC class II genes and is essential for their expression. The DNA-binding domain of RFX is the central domain of the protein and binds ssDNA as either a monomer or homodimer. It recognize X-boxes (DNA of the sequence 5'-GTNRCC(0-3N)RGYAAC-3', where N is any nucleotide, R is a purine and Y is a pyrimidine) using a highly conserved 76-residue DNA-binding domain (DBD).

 51-138 3.14e-28

RFX1 transcription activation region; The RFX family is a family of winged-helix DNA binding proteins. RFX1 is a regulatory factor essential for expression of MHC class II genes. This region is to found N terminal to the RFX DNA binding region (pfam02257) in some mammalian RFX proteins, and is thought to activate transcription when associated with DNA. Deletion analysis has identified the region 233-351 in human RFX1 as being required for maximal activation.
