Structure of a truncated form of leucine zipper II of JIP3 reveals an unexpected antiparallel coiled-coil arrangement
This study highlights that N-terminal truncation of LZII can change its coiled-coil orientation without affecting its overall stability. Further, a conserved buried asparagine residue was pinpointed as a possible structural determinant for this dramatic structural rearrangement. Thus, LZII of JIP3/4 is a versatile structural motif, modifications of which can impact partner recognition and thus biological function.
