Intraflagellar transport protein 88 homolog is a protein that in humans is encoded by the IFT88 gene. It is mapped to 13q12.11. This gene encodes a member of the tetratrico peptide repeat (TPR) family. The encoded protein is involved in cilium biogenesis. Mutations of a similar gene in mouse can cause polycystic kidney disease. Several transcript variants encoding distinct isoforms have been identified for this gene.
