BTB/POZ domain-containing protein KCTD17 (KCTD17)

Is a positive regulator of ciliogenesis, playing a crucial role in the first steps of axoneme expansion. It functions as a substrate-adapter for CUL3-RING ubiquitin ligase complexes which mediate the ubiquitination and subsequent proteasomal degradation of TCHP, a protein involved in ciliogenesis down-regulation (PubMed:25270598).

May be involved in endoplasmic reticulum calcium ion homeostasis (PubMed:25983243). .
