Endogenous expression of CUL4 E3 ligase in testes and Leydig cells. Representative immunoblots showing the endogenous expression of ClC-2 (A), CUL4A (B), CUL4B (C), DDB1 (D), and CRBN (E) in lysates prepared from mouse testes or cultured mouse Leydig cells. Approximately 30 µg of protein was loaded into each lane.
