Kinesin-like protein KIF3B is a protein that in humans is encoded by the KIF3B gene. [5] [6] KIF3B is an N-type protein that complexes with two other kinesin proteins to form two-headed anterograde motors. [7] First, KIF3B forms a heterodimer with KIF3A (kinesin-like protein KIF3A); (KIF3A/3B), that is membrane-bound and has ATPase activity. Then KIFAP3 (KAP3, kinesin superfamily associated protein–3) binds to the tail domain to form a heterotrimeric motor. [7] This motor has a plus end-directed microtubule sliding activity that exhibits a velocity of ~0.3 μm/s a. [8] There are 14 kinesin protein families in the kinesin superfamily and KIF3B is part of the Kinesin-2 family, of kinesins that can all form heterotrimeric complexes. [9] Expression of the three motor subunits is ubiquitous. The KIG3A/3B/KAP3 motors can transport 90 to 160 nm in diameter organelles. [7]

Contents

There are many orthologous KIF3B genes that are expressed in Drosophila , the sea urchin, Bos taurus , Canis familiaris , Equus caballus , Felis catus , Macaca mulatta , Mus musculus , Pan troglodytes , and Rattus norvegicus .

Function

The heterotrimeric KIF3B/KIF3A/KAP3 motor machinery functions in the intracellular transport of multiple different molecules such as β-catenin and MT1-MMP. [10] [11] KIF3B activity has been implicated with various cellular processes such as intracellular movement of organelles, intraflagellar transport, chromosome movement during mitosis and meiosis, and cellular interaction with the extracellular matrix. [6] [12] [13]

KIF3B also regulates the interaction of cancer cells with the extracellular matrix (ECM), in particular the transport of MT1-MMP to the cancer cell front is essential for collagen fiber matrix realignment and degradation. [14] [15]

Interactions

KIF3B has been shown to interact with the SMC3 subunit of the cohesin complex and with RAB4A. [16]
