The function of ENSG00000118965 (WDR35, WD repeat domain 35) is as follows. 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 (PubMed:21473986, PubMed:28400947, PubMed:29220510, PubMed:36775821). May promote CASP3 activation and TNF-stimulated apoptosis. {ECO:0000269|PubMed:20193664, ECO:0000269|PubMed:21473986, ECO:0000269|PubMed:28400947, ECO:0000269|PubMed:29220510, ECO:0000269|PubMed:36775821}.
