General annotation (Comments)

Function

Component of the centralspindlin complex that serves as a microtubule-dependent and Rho-mediated signaling required for the myosin contractile ring formation during the cell cycle cytokinesis. Essential for cytokinesis in Rho-mediated signaling. Required for the localization of ECT2 to the central spindle. Plus-end-directed motor enzyme that moves antiparallel microtubules in vitro. Ref.7 Ref.9 Ref.20

Subunit structure

Heterotetramer of two molecules each of RACGAP1 and KIF23. Found in the centralspindlin complex composed of RACGAP1 and KIF23. Interacts with RACGAP1; the interaction is direct. Interacts with ECT2 and PRC1. Interacts with ANXA11 during cytokinesis. Interacts with BIRC6/bruce and USP8/UBPY. Interacts with ARF6, forming heterodimers and heterotetramers. Ref.4 Ref.5 Ref.6 Ref.7 Ref.9 Ref.11 Ref.15 Ref.20

Subcellular location

Nucleus. Cytoplasmcytoskeletonspindle. Midbody. Note: Localizes to the interzone of mitotic spindles. Detected at the midbody during later stages of mitotic cytokinesis. Ref.6 Ref.9 Ref.20

Post-translational modification

Ubiquitinated. Deubiquitinated by USP8/UBPY. Ref.11

Sequence similarities

Belongs to the kinesin-like protein family.

Contains 1 kinesin-motor domain.
