Abstract

Kinesin is a microtubule-based motor protein involved in organelle transport in neuronal and nonneuronal cells. Although a single kinesin motor has been thought to serve all cell types, we document here that neurons express a second conventional kinesin heavy chain (nKHC) that is 65% identical in amino acid sequence to the ubiquitously expressed kinesin heavy chain (uKHC). By preparing antibodies which distinguish between the two KHCs, we demonstrate that nKHC is a nucleotide-dependent microtubule-binding protein which partially cofractionates with membrane organelles. Immunolocalization experiments show that nKHC is distributed throughout the CNS but is highly enriched in subsets of neurons. In hippocampal neurons in culture, uKHC is distributed uniformly throughout the neuron, whereas nKHC is selectively concentrated in the cell body. These results demonstrate that mammalian neuronal tissue contains two conventional kinesin motors which may serve distinct functions in microtubule-based transport.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In mammals, kinesin-I polypeptide components are encoded by three KHC genes (KIF5A, KIF5B, KIF5C) and three KLC genes (KLC1, KLC2, KLC3).

    “In mammals, the polypeptide components of kinesin-I are encoded by three KHC genes, KIF5A, KIF5B, and KIF5C (Gudkov et al. 1994; Niclas et al. 1994; Nakagawa et al. 1997; Xia et al. 1998), and three KLC genes, KLC1, KLC2, and KLC3 (Lamerdin et al. 1996; Rahman et al. 1998).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
