background:
Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex involved in interferon response. The BCR(KLHL20) E3 ubiquitin ligase complex mediates the ubiquitination of DAPK1, leading to its degradation by the proteasome, thereby acting as a negative regulator of apoptosis. Also acts as a regulator of endothelial migration during angiogenesis by controlling the activation of Rho GTPases.
Function:
Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex involved in interferon response. The BCR(KLHL20) E3 ubiquitin ligase complex mediates the ubiquitination of DAPK1, leading to its degradation by the proteasome, thereby acting as a negative regulator of apoptosis. Also acts as a regulator of endothelial migration during angiogenesis by controlling the activation of Rho GTPases.
Subunit:
Component of the BCR(KLHL20) E3 ubiquitin ligase complex, at least composed of CUL3, KLHL20 and RBX1. Interacts with DAPK1. Interacts with F-actin. Interacts with IFN-gamma (IFNG).
Subcellular Location:
Cytoplasm, perinuclear region. Nucleus. Note=Localizes in the perinuclear region in normal conditions. Following IFN-alpha or IFN-gamma treatment, it is relocalized and sequestrated to the PML nuclear bodies, preventing DAPK1 ubiquitination.
Similarity:
Contains 1 BACK (BTB/Kelch associated) domain.
Contains 1 BTB (POZ) domain.
Contains 6 Kelch repeats.
