STRUCTURE OF APO-CALMODULIN BOUND TO UNCONVENTIONAL MYOSIN V
Overview
A 2.5-A resolution structure of calcium-free calmodulin (CaM) bound to the, first two IQ motifs of the murine myosin V heavy chain reveals an unusual, CaM conformation. The C-terminal lobe of each CaM adopts a semi-open, conformation that grips the first part of the IQ motif (IQxxxR), whereas, the N-terminal lobe adopts a closed conformation that interacts more, weakly with the second part of the motif (GxxxR). Variable residues in the, IQ motif play a critical role in determining the precise structure of the, bound CaM, such that even the consensus residues of different motifs show, unique interactions with CaM. This complex serves as a model for the lever, arm region of many classes of unconventional myosins, as well as other IQ, motif-containing proteins such as neuromodulin and IQGAPs.
