Binding of BMS493 and a protein protein complex consisting of mutant __NODE__ ( deletion with its A/B region deleted ) and of mutant __NODE__ ( deletion with its A/B region deleted ) decreases binding of a protein fragment ( 624 828 ) containing a LXXLL motif from __NODE__ protein and a protein protein complex consisting of mutant __NODE__ ( deletion with its A/B region deleted ) and of mutant __NODE__ ( deletion with its A/B region deleted ) .
