Function

Localisation of the clathrin light chain, AP-2 clathrin adaptor, dynamin and RAB-5 endocytic proteins overlaps with a morphologically discrete periciliary membrane compartment associated with sensory cilia(PMID: 22342749). STAM-1 and RAB-5 collocate in the cell bodies and ciliary bases of polycystin-expressing neurons (Ppkd-2::STAM-1A:: GFP and Ppkd-2::mRFP::RAB-5, Figure 3, B–D). Combined, these data indicate that C. elegans STAM-1A colocalizes with HGRS-1 on the early endosome at the ciliary base, where they may participate in endocytic sorting of LOV-1 and PKD-2(17581863).

Model organism evidence

Mus musculus (1 reference)

Systematic proteomic analysis of LRRK2-mediated Rab GTPase phosphorylation establishes a connection to ciliogenesis.

C. elegans (3 references)

How this is achieved is unclear, but protein transport in cilia (intraflagellar transport, IFT) plays an important role.

Transmembrane protein OSTA-1 shapes sensory cilia morphology via regulation of intracellular membrane trafficking in C.
