abstract：:Kinesin light chain 3 (KLC3) is the only known kinesin light chain expressed in post-meiotic male germ cells. We have reported that in rat spermatids KLC3 associates with outer dense fibers and mitochondrial sheath. KLC3 is able to bind to mitochondria in vitro and in vivo employing the conserved tetratrico-peptide re...
