The KCTD1 BTB domains, closely related to KCTD15, form pentamers. Pssm-ID: 349696 Cd Length: 99 Bit Score: 40.75 E-value: 2.50e-04

BTB (Broad-Complex, Tramtrack and Bric a brac)/POZ (poxvirus and zinc finger) domain found in potassium channel tetramerization domain-containing protein 2 (KCTD2); KCTD2 is a BTB/POZ domain-containing protein that functions as an adaptor of Cullin3 E3 ubiquitin ligase. It suppresses gliomagenesis by destabilizing c-Myc. The BTB/POZ domain, also known as tetramerization (T1) domain, is a versatile protein-protein interaction motif that facilitates homodimerization or heterodimerization. KCTD family BTB domains can adopt a wide range of oligomerization geometries, including homodimerization, tetramerization, and pentamerization. KCTD5 and KCTD17 BTB domain, highly similar to KCTD2, form pentamer structures. Pssm-ID: 349697 [Multi-domain] Cd Length: 105 Bit Score: 40.35 E-value: 3.93e-04
