Summary from NCBI RefSeq

[Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is part of the intraflagellar transport complex B and is necessary for the function of motile and sensory cilia. Defects in this gene are a cause of asphyxiating thoracic dystrophy 2 (ATD2). Three transcript variants encoding two different isoforms have been found for this gene.[provided by RefSeq, Jun 2010]

Summary text for additional MGI annotations

• Automated translation to GO terms of SwissProt keywords that describe Ift80 indicates that it:
  • is located in the following cellular components:
    • cell projection
    • cytoplasm
    • cytoskeleton
• Annotations directly to molecular function for the gene Ift80 indicate that MGI curators have found no experimental data [literature] to support further annotation to this category at this time.
