Q14999; Q8N3Y1
CRL7Fbxw8 is an E3 ubiquitin ligase complex, containing cullin 7 as a scaffold, the F-box protein Fbxw8 as a substrate receptor, the Skp1 adaptor, and the ROC1/Rbx1 RING finger protein for working with E2 enzyme to facilitate ubiquitin transfer

genetic depletion and inhibition of cytosolic enzyme enhance neurite extension and branching in developing neurons
physiological function

Q14999; Q8N3Y1
the enzyme plays a role in growth control and cancer cell proliferation
physiological function
the enzyme plays an essential role in cell cycle progression
physiological function
-
the enzyme regulates neurite morphogenesis during neurodevelopment. The enzyme is vital for regulation of neuritogenesis. The cullin-RING E3 ubiquitin ligase 4-Crbn complex regulates doublecortin stability, affecting microtubule dynamics. Cullin 4a and cullin 4b, the core scaffold proteins of the enzyme, exhibit high expression and activation within the cytosol of developing neurons, regulated by neuronal stimulation through N-methyl D-aspartate receptor signaling
physiological function
the multiprotein CRLpVHL complex is necessary for APOBEC3 protein degradation (A3A, -B, -C, D, F, G, and -H). The enzyme more effectively induces degradation of nuclear, procancer APOBEC3 (A3B) than the cytoplasmic, antiretroviral APOBEC3 (A3G) protein
