Intraflagellar transport protein 88 homolog is a protein that in humans is encoded by the IFT88 gene.^[1][2]

Function

This gene encodes a member of the tetratrico peptide repeat (TPR) family. Mutations of a similar gene in mouse can cause polycystic kidney disease. Two transcript variants encoding distinct isoforms have been identified for this gene.^[2] In 2012 a mutation was found to be responsible for a novel form of ciliopathy and anosmia in humans capable of remedy in mice by adenoviral mediated gene therapy.^[3]

Interactions

IFT88 has been shown to interact with BAT2.^[4]
