What pLDDT means and how to read it

Function

Activates transcription from class II MHC promoters. Recognizes X-boxes. Mediates cooperative binding between RFX and NF-Y. RFX binds the X1 box of MHC-II promoters

Subunit structure

Homodimer. The RFX heterotetrameric complex consists of 2 molecules of RFX5 and one each of RFXAP and RFX-B/RFXANK; with each subunit representing a separate complementation group. Interacts (via PxLPxI/L motif) with RFXANK (via ankyrin repeats); the interaction is direct. RFX forms cooperative DNA binding complexes with X2BP and CBF/NF-Y. RFX associates with CIITA to form an active…
