Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived human Cullin 4a recombinant protein (Position: M494-A759). (reported region: M494-A759).
- Molecular weight context: reported MW: 88 kDa; calculated MW: nan
- Reactivity: Human,Mouse,Rat
- Applications: ELISA, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
cullin 4A. Cullin-4A is a protein that in humans is encoded by the CUL4A gene. It belongs to the cullin family of ubiquitin ligase proteins and is highly homologous to the CUL4B protein. CUL4A regulates numerous key processes such as DNA repair, chromatin remodeling, spermatogenesis, haematopoiesis and the mitotic cell cycle. As a result, CUL4A has been implicated in several cancers and the pathogenesis of certain viruses including HIV. Interestingly, a component of a CUL4A complex, Cereblon, was discovered to be a major target of the teratogenic agent thalidomide. Functional note: Core component of multiple cullin-RING-based E3 ubiquitin-protein ligase complexes which mediate the ubiquitination of target proteins. As a scaffold protein may contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. The E3 ubiquitin-protein ligase activity of the complex is dependent on the neddylation of the cullin subunit and is inhibited by the association of the deneddylated cullin subunit with TIP120A/CAND1. The functional specificity of the E3 ubiquitin-protein ligase complex depends on the variable substrate recognition component. DCX (DET1-COP1) s ubiquitination of JUN. DCX (DDB2) s ubiquitination of XPC. DCX (DDB2) ubiquitinates histones H3-H4 and is required for efficient histone deposition during replication-coupled (H3.1) and replication-independent (H3.3) nucleosome assembly, probably by facilitating the transfer of H3 from ASF1A/ASF1B to other chaperones involved in histone deposition. DCX (DTL) plays a role in PCNA-dependent polyubiquitination of CDT1 and MDM2-dependent ubiquitination of TP53 in response to radiation-induced DNA damage and during DNA replication. In association with DDB1 and SKP2 probably is involved in ubiquitination of CDKN1B/p27kip. Is involved in ubiquitination of HOXA9. DCX (DTL) s autoubiquitination of DTL.
Research relevance and current trends
- Proteasome / Ubiquitin: Researchers commonly examine how CUL4A relates to this theme using model systems and orthogonal readouts.
- Proteolysis/Ubiquitin: Researchers commonly examine how CUL4A relates to this theme using model systems and orthogonal readouts.
- SCF Complex E3 Ligase: Researchers commonly examine how CUL4A relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative CUL4A levels across conditions; band patterns may reflect isoforms and processing.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
