This domain is found in human Kinesin-like protein KIF21A and similar eukaryotic sequences. KIF21A is a microtubule-binding motor protein probably involved in neuronal axonal transport. Mutations in this protein are associated with ocular abnormalities. This domain, which is found associated to Pfam:PF00225 and several Pfam:PF00400 repeats, folds into two long alpha-helices [1].
