Gene Summary
Kinesin-like protein at 68D (Klp68D) encodes the kinesin-2β motor subunit of the heterotrimeric kinesin-2. It associates with the products of Klp64D and Kap3. It plays an essential role in the sensory cilia assembly, microtubule organization in dendrites, and axonal transport. [Date last reviewed: 2019-03-14] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
KINESINS -
Kinesin superfamily proteins (KIFs) are microtubule motor proteins which use the hydrolysis of ATP to drive directional movement along microtubules. KIFs possess a well-conserved 360 residue globular head domain which binds and hydrolyses ATP and interacts with microtubules. Many KIFs homodimerize via coiled-coil interactions in the stalk region. KIFs bind cargo through their variable tail regions and are involved in transporting organelles, protein complexes, mRNAs and the movement of spindles and chromosomes during cell division. (Adapted from FBrf0219884).
Protein Function (UniProtKB)
Plus-end directed microtubule motor that may be used for anterograde axonal transport and could conceivably move cargos in fly neurons different than those moved by kinesin heavy chain or other plus-end directed motors.
(UniProt, P46867)

    Molecular and biochemical properties of Klp68D suggest it may be used for anterograde axon transport and could move cargoes in neurons different to those moved by kinesin heavy chain or other plus-end directed motors.

    Klp68D has been cloned, partially sequenced and its expression pattern analysed.
