Kinesin family member 15 is a protein that in humans is encoded by the KIF15 gene.[1]

This gene encodes a motor protein that is part of the kinesin superfamily. KIF15 maintains half spindle separation by opposing forces generated by other motor proteins. KIF15 co-localizes with microtubules and actin filaments in both dividing cells and in postmitotic neurons.[1]

Function

KIF15 (also known as Kinesin-12 and HKLP2) is a motor protein expressed in all cells during mitosis and in postmitotic neurons undergoing axon growth.[2] KIF15 maintains bipolar microtubule spindle apparatus in dividing cells and shares redundant functions with KIF11.[3] KIF15 is thought to promote spindle assembly by cross-linking and sliding along microtubules creating a separation between centrosomes. HeLa cells depleted of KIF11, with reduced microtubule dynamics, are able to form bipolar spindles from acentrosomal asters in a KIF15 dependent manner.[4][5]

Function in neurons

KIF15 restricts the movement of short microtubules into growing axons by generating forces on microtubules which counteract those generated by cytoplasmic dynein.[6][7] KIF15, together with KIF23 become enriched in dendrites as neurons mature to promote the transport of minus-end distal microtubules into nascent dendrites.[6]

Interactions

KIF15 has been shown to interact with TPX2. Both these dimers cooperate to slide along microtubules and maintain bipolar spindles.[8][9]
