CUL3

CUL3

A gene on chromosome 2q36.2 that encodes cullin-3, a core protein of multiple cullin-RING-based BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complexes, which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Cullin-3 may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The ubiquitin-protein ligase activity of the complex depends on neddylation of the cullin subunit, and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1.

Mendelian forms of hypertension and germline mutations causing early-onset hypertension have highlighted biological pathways that involve renal salt handling (WNK1, WNK4, KLHL3, and CUL3), ion transport (CACNA1D, CACNA1H, KCNJ5, SCNN1B, and SCNN1G), corticosteroidogenesis (CYP11B2, HSD11B2, NR3C2, CYP11B1, and CYP17A1), and vascular tone (PDE3A) to regulate blood [41-44].

Functional activity of Nrf2 strongly depends on its regulation by the Keapl adaptor protein, in the absence of electrophiles or oxidants, Keapl binds to and sequesters Nrf2 in the cytoplasm, resulting in Nrf2 ubiquitination by Cul3 and degradation in the proteasome.

The order of thermal stabilities these compounds were found: CuL4 > CuL1 > CuL6 > CuL2, 5 > CuL3 > L5 > L1, 2, 4> L3 > L6, which may be attributed to the specific chemical structures of the synthesized ligands and copper(II) complexes.
