Kinesin is a microtubule-associated force-producing protein that may play a role in organelle transport (Probable). The light chain may function in coupling of cargo to the heavy chain or in the modulation of its ATPase activity (Probable). Recruits unc-83 (within the unc-83-unc-84 LINC complex) to the nuclear envelope during nuclear migration to mediate the link between the nuclear envelope and the microtubule cytoskeleton in hypodermal precursor cells (PubMed:19605495, PubMed:27697906). Oligomeric complex composed of two heavy chains and two light chains (Probable). Interacts with unc-83; the interaction is direct (PubMed:19605495). Interacts with unc-33; the interaction regulates unc-33 neurite localization (PubMed:16236031). Recruited to the nuclear envelope by unc-83 during nuclear migrations. The light chain is composed of three structural domains: a large globular N-terminal domain which may be involved in binding to kinesin heavy chains, a central alpha-helical coiled-coil domain that mediates the light chain dimerization; and a small globular C-terminal which may play a role in regulating mechanochemical activity or attachment of kinesin to membrane-bound organelles. RNAi-mediated knockdown results in defects in nuclear migration in hyp7 hypodermal precursor cells (PubMed:27697906). RNAi-mediated knockdown in a dhc-1 (js319) mutant background results in defective nuclei migrations in larval hypodermal P-cells (PubMed:27697906). Belongs to the kinesin light chain family.
