Background Information
Cullin-RING ligases (CRLs) complexes participate in the regulation of diverse cellular processes, including cell cycle progression, transcription, signal transduction and development (PMID: 21816341)(PMID: 21554755). Serving as the scaffold protein, cullins are crucial for the assembly of ligase complexes, which recognize and target various substrates for proteosomal degradation. Two cullin 4 (CUL4) proteins, CUL4A (87 kDa) and CUL4B(104 kDa), are two members in cullin family with 83% of identity. Mutations in human CUL4B are one of the major causes of X-linked mental retardation. Cul4b knockout mice demonstrated that CUL4B is indispensable for embryonic development in the mouse (PMID: 22606329). Proteintech's CUL4B antibody 20882-1-AP can specifically recognize CUL4B.

The species listed in Tested Reactivity are in-house verified and applicable species. For unlisted species, please refer to the homology analysis of the immunogen sequence and related species. For rabbit polyclonal antibodies, homology >70% is recommended. For mouse monoclonal antibodies and rabbit recombinant antibodies, homology >90% is recommended. Generally, the higher the homology, the greater the applicability. However, there will be certain differences in protein expression in different species, tissues or cells. Therefore, the homology analysis results are for reference only and do not serve as a guarantee.
