Kinesin is a microtubule-associated force-producing protein that plays a role in organelle transport. The light chain functions in coupling of cargo to the heavy chain or in the modulation of its ATPase activity. Through binding with PLEKHM2 and ARL8B, recruits kinesin-1 to lysosomes and hence direct lysosomes movement toward microtubule plus ends. Oligomeric complex composed of two heavy chains and two light chains. Interacts (via TPR repeats) with PLEKHM2. Mutants show a progressive hearing loss with an increase in auditory brainstem response (ABR) thresholds with age, mostly affecting low frequencies, with a sensorineural (not conductive) pathology. At one month old, there is extensive loss of outer hair cell (OHC) hair bundles. Belongs to the kinesin light chain family.
