||DNA-binding protein RFXANK
||Ankyrin repeat family A protein 1, Regulatory factor X subunit B, RFX-B, Regulatory factor X-associated ankyrin-containing protein | ANKRA1, RFXB

||Activates transcription from class II MHC promoters. Activation requires the activity of the MHC class II transactivator/CIITA. May regulate other genes in the cell. RFX binds the X1 box of MHC-II promoters (PubMed:9806546, PubMed:10072068, PubMed:10725724). May also potentiate the activation of RAF1 (By similarity).
