Kinesin light-chain KLC3 expression in testis is restricted to spermatids.

ABSTRACT: Kinesins are tetrameric motor molecules, consisting of two kinesin heavy chains (KHCs) and two kinesin light chains (KLCs) that are involved in transport of cargo along microtubules. The function of the light chain may be in cargo binding and regulation of kinesin activity. In the mouse, two KLC genes, KLC1 and KLC2, had been identified. KLC1 plays a role in neuronal transport, and KLC2 appears to be more widely expressed. We report the cloning from a testicular cDNA expression library of a mammalian light chain, KLC3. The KLC3 gene is located in close proximity to the ERCC2 gene. KLC3 can be classified as a genuine light chain: it interacts in vitro with the KHC, the interaction is mediated by a conserved heptad repeat sequence, and it associates in vitro with microtubules.
