Protein Family Annotation Pfam Database Homepage

Chains Pfam Accession Pfam Identifier Pfam Description Type Source
E PF02214 BTB_2 BTB/POZ domain Domain 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]. PFAM PF02214
A PF00248 Aldo_ket_red Aldo/keto reductase family Domain This family includes a number of K+ ion channel beta chain regulatory domains - these are reported to have oxidoreductase activity [2]. PFAM PF00248
