Intraflagellar transport protein 88 homolog is a protein that is encoded by the IFT88 gene.^[5]^[6]

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.^[6] 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.^[7]

Interactions

IFT88 has been shown to interact with BAT2 and WDR62.^[8]^[9] WDR62 is required for IFT88 localization to the cilia basal body and the cilia axoneme. ^[10]
