X-RAY DIFFRACTION

Starting Model(s)

Initial Refinement Model(s)
Type	Source	Accession Code	Details
in silico model	AlphaFold		Models of the individual MBP and NR2F6 domains were prepared using AlphaFold2 Colab. The Process Predicted Model of the Phenix software was used to process these models, and subsequently these processed models were used as search components in the molecular replacement.
