Background Information

Cullin-RING-based BCR (BTB-CUL3-RBX1) E3 ligase are the largest family of ubiquitin ligases which mediate the ubiquitination and subsequent proteasomal degradation of target proteins. One of seven cullin proteins serves as a scaffold protein for the assembly of the multisubunit ubiquitin ligase complex. CUL3 (Cullin-3) ubiquitin ligase complex targets multiple substrate for ubiquitination including cyclin E and of cyclin D1. Defects in CUL3 are the cause of Pseudohypoaldosteronism type 2E (PHA2E) characterized by severe hypertension, hyperkalemia, hyperchloremia, hyperchloremic metabolic acidosis, and correction of physiologic abnormalities by thiazide diuretics.

10ug load of protein. Cells lysed in RIPA buffer then added to 2X Laemmli buffer for denaturing. Heated at 95deg for 10 minutes as well.Multiple bands, but all follow same pattern. Assumed the band at ~75 kD was the correct one.
