What is the official name of the IFT80 gene?
The official name of this gene is “intraflagellar transport 80.”
IFT80 is the gene's official symbol. The IFT80 gene is also known by other names, listed below.

What is the normal function of the IFT80 gene?
The IFT80 gene provides instructions for making a protein that is part of a group (complex) called IFT complex B. This complex is found in cell structures known as cilia. Cilia are microscopic, finger-like projections that stick out from the surface of cells. IFT complex B is involved in a process called intraflagellar transport (IFT), by which materials are carried within cilia. Specifically, this complex helps transport materials from the base of cilia to the tip.
IFT is essential for the assembly and maintenance of cilia. These cell structures play central roles in many different chemical signaling pathways, including a series of reactions called the Sonic Hedgehog pathway. These pathways are important for the growth and division (proliferation) and maturation (differentiation) of cells. In particular, Sonic Hedgehog appears to be essential for the proliferation and differentiation of cells that ultimately give rise to cartilage and bone.
Does the IFT80 gene share characteristics with other genes?
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
