Kinesin-associated protein 3 (IPR008658)

Short name: KAP3

Overlapping homologous superfamilies


Family relationships



This family consists of kinesin-associated protein 3 (KAP3, also known as SMAP). In human and mouse, KAP3 is involved in tethering the chromosomes to the spindle pole and in chromosome movement. It binds to the tail domain of the KIF3A/KIF3B heterodimer to form a heterotrimeric KIF3 complex and may regulate the membrane binding of this complex [PMID: 8710890, PMID: 9506951].
