Figure 6From: Crk and CrkL adaptor proteins: networks for physiological and pathological signalingSequence alignment of various Crk species. Chicken Crk is unique in possessing a PFY motif. As alluded to in the text, this may imply that chicken Crk is uniquely regulated by prolyl cis-trans isomerization. Shown in the right side of the figure is a schematic representaion depicting accessibility in the different conformations.Back to article page
