Kinesin-like protein KIF22 is a protein that in humans is encoded by the KIF22 gene.[3][4][5]

The protein encoded by this gene is a member of kinesin-like protein family. This family of proteins are microtubule-dependent molecular motors that transport organelles within cells and move chromosomes during cell division. The C-terminal half of this protein has been shown to bind DNA. Studies with the Xenopus homolog suggests an essential role in metaphase chromosome alignment and maintenance.[5]


KIF22 has been shown to interact with SIAH1.[6]

Clinical relevance[edit]

Mutations in this gene have been shown to cause developmental disorders such as Spondyloepimetaphyseal dysplasia with joint laxity.[7]
