Substrate-recognition component of some cullin-RING-based BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex. The BCR(KLHL17) mediates the ubiquitination and subsequenct degradation of GLUR6. May play a role in the actin-based neuronal function.
Specificity
Natural and recombinant Human Kelch-like protein 17
Interacts with F-actin; the interaction disruptes the F-actin structures and leads to marked changes of neuronal morphology. Component of a complex, composed of PDZK1, SYNGAP1, KLHL17 and NMDA receptors. Interacts directly with PDZK1 (via PDZ1 domain); the interaction is important for integrity of actin cytoskeleton structures in neurons. Interacts with DLG4 and SYNGAP1. Interacts (via kelch repeats) with GRIK2 (via C-terminus); the interaction targets GRIK2 for degradation via ubiquitin-proteasome pathway. Interacts with GRIK1. Interacts with (via BTB domain) CUL3; the inteaction regulates surface GRIK2 expression.
