MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a intraflagellar transport protein important for intracellular transport. The encoded protein forms part of a complex involved in trafficking of proteins from the Golgi body, including recycling of immune signalling components (Finetti et al., PubMed: 19855387). This gene is part of a complex set of sense-antisense loci that may be co-regulated. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome 14.[provided by RefSeq, Jun 2012]
PHENOTYPE: Mice homozygous for a null mutation die before birth. Mice with conditional loss in renal collecting ducts lack primary cilia and develop renal cysts. [provided by MGI curators]
