intraflagellar transport 20 homolog (intraflagellar transport protein 20, hIFT20, IFT20)

Function

• part of intraflagellar transport particles involved in ciliary process assembly
• may play a role in trafficking of ciliary membrane proteins from the Golgi complex to the cilium
• component of IFT complex B
• interacts directly with IFT57 & KIF3B/Kinesin2 subunit (putative)

Compartment

• Golgi, cis-Golgi, centrosome, centriole (putative)
• cell projection, cilium basal body (putative)
• present at the centrosomes during the cell cycle & associated with the proximal portion of the mother centriole & the lateral aspect of the daughter centriole
• associated with basal body at the base of primary cilia (putative)

Alternative splicing

named isoforms=3

Expression

expressed in almost all tissues

More general terms

Component of
