• Actin & cytoskeleton regulation
• Signaling (Hedgehog, GPCRs, ion channels)

Function

IFT121. IFT complex A component, endogenous WDR35 localizes to cilia and centrosomes throughout the developing embryo and human and mouse fibroblasts lacking the protein fail to produce cilia. Human and mouse homozygouse mutations in WDR35 cause ciliopathy short-rib polydactyly syndrome (22987818). Heterozygous mutations shown to cause cranioectodermal dysplasia-2. OMIM:613602. Interacts with RagA, mTORC1 activator (30570184)
