Cullin-ring ligases
WebJan 3, 2024 · CULLIN1 consists of an N-terminal helical region (NTD) that is 415 amino acids long and a C-terminal globular α/β domain (CTD). Three Cullin repeats—that is, a five-helix structural motif arranged in a regularly repeated manner, culminating in an arc-shaped architecture stretching ~100 angstroms—make up the NTD. WebCullin 3 (CUL3) is the scaffold of Cullin3 Ring E3-ligases (CRL3s), which use various BTB-adaptor proteins to ubiquitinate numerous substrates targeting their proteasomal degradation. CUL3 mutations, responsible for a severe form of familial hyperkalemia and hypertension (FHHt), all result in a deletion of exon 9 (amino-acids 403-459) (CUL3-∆9).
