Binding of __NODE__ 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 ) increases 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 ) .
