General annotation (Comments)

Function	Kinesin is a microtubule-associated force-producing protein that may play a role in organelle transport. The light chain may function in coupling of cargo to the heavy chain or in the modulation of its ATPase activity By similarity.
Subunit structure	Oligomeric complex composed of two heavy chains and two light chains By similarity.
Sequence similarities	Belongs to the kinesin light chain family. Contains 6 TPR repeats.
