These data show that the alpha - helix domain of p57 ( Kip2 ) , which is conserved in the Cip / Kip proteins , is implicated in protein - protein interaction and confers a specific regulatory mechanism , outside of their Cdk - inhibitory activity , by which the p57 ( Kip2 ) family members positively act on myogenic differentiation .
