1.X.1.  The Intraflagellar Transporter-A Complex (Ift-A) Family

The Ift-A complex appears to be a multicomponent complex that functions to transport flagellar/ciliary membrane proteins under the eukaryotic ciliary membrane.  As a component of the IFT complex A (IFT-A), a complex required for retrograde ciliary transport and entry into cilia of G protein-coupled receptors (GPCRs), it is involved in ciliogenesis and ciliary protein trafficking (Mill et al. 2011, Duran et al. 2017, Takahara et al. 2018). Not all of the ItfA complex have been identified.  Here, we list only a few of them.
