In voltage-gated K+ channels this domain is responsible for subfamily-specific assembly of alpha-subunits into functional tetrameric channels [1]. In KCTD1 (Swiss:Q719H9) this domain functions as a transcriptional repressor [2]. It also mediates homomultimerisation of KCTD1 and interaction of KCTD1 with the transcription factor AP-2-alpha [2-3].	Domain
