KINESIN heavy chain and kinesin-related polypeptides (KRPs) comprise a family of motor proteins with diverse intracellular transport functions1–7. Using pan-kinesin peptide antibodies that react with these proteins8,9, we haven previously purified from sea urchin eggs a trimeric microtubule-binding and bundling protein, KRP(85/95) (ref. 8) comprising subunits of Mr115,000 (115K), 95K and 85K. We report here that kinesin-related genes encode the 85K and 95K subunits, and that the protein can be…

Mapping of the interaction domains of the two proteins by two-hybrid analyses indicates that Kar3p and Cik1p associate in a highly specific manner along the lengths of their respective coiled-coil domains, demonstrating that the Kar3-Cik1 complex has a novel heterodimeric structure not observed previously for kinesin complexes.

It is predicted that native KIF1A can exist as both an inactive monomer and an active homodimer formed in part through its neck coiled-coil domain.

It is found that the 120-kDa HeLa cell conventional kinesin is an active motor that induces microtubule gliding at ∼30 μm/min at room temperature and does not contain light chains, although light chains were detected in other fractions.

The general belief is that variability within the tail domains reflects different functions or binding affinities of the respective motors, and is indeed supported by experimental evidence.

Fractionation and Characterization of Kinesin II Species in Vertebrate Brain
- BiologyTraffic

This work isolated nucleotide‐dependent, microtubule‐binding proteins from 13‐day chick embryo brain and identified three KIF species, the most abundant species, kinesin I, which exhibited the expected long range micro tubule gliding activity, and KIF1C, which did not move microtubules.
Kinesin-II, the heteromeric kinesin
- Biology, ChemistryCellular and Molecular Life Sciences CMLS

A novel feature of these motors is that the activities of several kinesin-II representatives are essential in the assembly of motile and nonmotile cilia, a role not attributed to any other kinesins.

- Biology, ChemistryJournal of cell science

A triplet of polypeptides, which the authors refer to as KRP(85/95), binds to purified sea urchin egg tubulin in an AMPPNP-enhanced, ATP-sensitive manner and induces the formation of microtubule bundles, and it is proposed that the triplet corresponds to a novel sea urchesin egg kinesin-related protein.

It is reported that, unlike antibodies to conventional kinesin, the peptide antibodies to the kines in motor domain immunofluorescently label spindles and kinetochores in mitotic tissue culture cells, suggesting that kinesIn-like proteins may have important roles in chromosome movement and mitosis.

The finding that sea urchin kinesin contains equimolar quantities of heavy and light chains, together with the aforementioned data on kinesIn morphology, suggests that native sea urchesin is a tetramer assembled from two light chains and two heavy chains.

Evidence is reported that conventional kinesin is associated with membranes which accumulate in MAs and interphase asters of early sea urchin embryos, and with vesicles that are distributed in the perinuclear region of coelomocytes, and which may function as a microtubule-based vesicle motor in some MAs, as well as in the interphase cytoplasm.
