BD Transduction Laboratories™ Purified Mouse Anti-KIF3A

The ability of the kinesin superfamily of motor proteins to hydrolyze ATP as they move progressively along microtubules is important for organelle transport and cell division. Kinesins are grouped according to the location of the motor domain in the N-terminal, middle, or C-terminal region of the protein. A family of N-terminal motor domain kinesin proteins includes KIF3A/3B, KRP85/95, and Klp68d/64. These proteins form heterodimeric two-headed motors that interact with kinesin associated protein (KAP). The KIF3A/3B/KAP3 heterotrimeric motor has plus-end directed microtubule sliding activity. This heterotrimeric motor is expressed ubiquitously and is used for anterograde transport of membranous organelles. KIF3A- and KIF3B-deficient mice have defects in the formation of the cilia located in the embryonic node. In addition, KIF3A localizes to the basal body of the connecting cilium axoneme and to vesicles at the pre-synaptic ribbon in photoreceptor cells. Thus, KIF3 motors are involved in microtubule-based formation and movement of cilia and the transport of synaptic vesicles.

This antibody is routinely tested by the Western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.
