摘要
The kinesin superfamily proteins (KIFs) are motor proteins that transport organelles and protein complexes in a microtubule- and ATP-dependent manner. We identified KIF26A as a new member of the murine KIFs. KIF26A is a rather atypical member as it lacks ATPase activity. Mice with a homozygous deletion of Kif26a developed a megacolon with enteric nerve hyperplasia. Kif26a-/- enteric neurons showed hypersensitivity for GDNF-Ret signaling, and we find that KIF26A suppressed GDNF-Ret signaling by direct binding and inhibition of Grb2, an essential component of GDNF/Akt/ERK signaling. We therefore propose that the unconventional kinesin KIF26A plays a key role in enteric nervous system development by repressing a cell growth signaling pathway.
