Kinesin family member 4A is a protein that in humans is encoded by the KIF4A gene. [5] [6]

Contents

Function

Kinesins, such as KIF4A, are microtubule-based motor proteins that generate directional movement along microtubules. They are involved in many crucial cellular processes, including cell division. [6]

Interactions

KIF4A has been shown to interact with HMG20B [7] and DNMT3B. [8]

Clinical significance

NTCP is the entry receptor for both Hepatitis B (HBV) and Hepatitis D viruses (HDV). [9] KIF4 was found to play an essential role in HBV and HDV infection through its regulation of the retrograde transport of NTCP from the cytoplasm to the cell surface where it acts as a receptor for HBV/HDV infection. [10]

<span class="mw-page-title-main">Kinesin-associated protein 3</span> Protein-coding gene in the species Homo sapiens

Kinesin-associated protein 3 (KAP3) is a protein that in humans is encoded by the KIFAP3 gene. It is a non-motor, accessory subunit which co-oligomerizes with the motor subunits KIF3A and KIF3B or KIF3C, to form heterotrimeric kinesin-2 motor proteins. Kinesin-2 KAP subunits were initially characterized in echinoderms and mice.

<span class="mw-page-title-main">KIF3B</span> Protein-coding gene in the species Homo sapiens

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