BTB/POZ domain-containing protein KCTD5

Gene

KCTD5

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Its interaction with CUL3 suggests that it may act as a substrate adapter in some E3 ligase complex. Does not affect the function of Kv channel Kv2.1/KCNB1, Kv1.2/KCNA2, Kv4.2/KCND2 and Kv3.4/KCNC4.

Domaini

The BTB (POZ) domain is atypical and mediates the formation of a homopentamer instead of a homotetramer. Homopentamerization is due to the presence of 4 residues in the BTB (POZ) domain: Leu-56, Gly-100, Val-112 and Ala-118.1 Publication
