From NCBI Gene:
This gene encodes a protein that belongs to a conserved family of potassium channel tetramerization domain (KCTD)-containing proteins. The encoded protein functions in ciliogenesis by acting as a substrate adaptor for the cullin3-based ubiquitin-conjugating enzyme E3 ligase, and targets trichoplein, a keratin-binding protein, for degradation via polyubiquitinylation. A mutation in this gene is associated with autosomal dominant myoclonic dystonia 26. [provided by RefSeq, Nov 2016]
Is a positive regulator of ciliogenesis, playing a crucial role in the initial steps of axoneme extension. It acts 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).

- Dystonia 26, myoclonic
Dystonia 26, myoclonic (DYT26): A form of dystonia, a disorder defined by the presence of sustained involuntary muscle contraction, often leading to abnormal postures. DYT26 is an autosomal dominant, progressive disorder characterized by a combination of non-epileptic myoclonic jerks and dystonia. Affected individuals manifest myoclonic jerks in the upper limbs during the first or second decade of life, and later develop dystonia with predominant involvement of the craniocervical regions and sometimes the trunk and/or lower limbs.
