Paired amphipathic helix repeat
This family contains the paired amphipathic helix repeat. The family contains the yeast SIN3 gene (also known as SDI1) that is a negative regulator of the yeast HO gene. This repeat may be distantly related to the helix-loop-helix motif, which mediate protein-protein interactions.
