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.
