Description

General description

Cullin-4 (Cul4) proteins are the core components of ubiquitin E3 ligases. Mammalian cells express two distinct but highly homologous cullin-4 proteins, cullin-4A and cullin-4B.

Cullin-4A is a protein encoded by CUL4A gene in humans.

Application

Anti-Cullin-4A antibody produced in rabbit is used for Immunofluorescence at a concentration of 10-20mg/mL using HeLa cells and is also used for western blotting at a concentration of 1-2μg/mL using HEK-293T cells expressing human Cullin-4A.

Biochem/physiol Actions

Cullin-4 (Cul4) proteins are components of ubiquitin E3 ligases that regulate cell cycle, genome stability, DNA replication and transcription. CUL4-based E3 ligase plays an important role for the repression of photomorphogenesis in plants (like Arabidopsis thaliana).

Cullin-4A (Cul4A) is involved in identifying specific targets for ubiquitylation. The Cul4A gene is known to be amplified and up-regulated in breast carcinoma and many other tumor types. Cul4A associates with damage-specific DNA binding proteins (DDB1 and DDB2). It functions as substrate recruiting factors for Cul4A-Roc1 ligases. Cul4A is known to ubiquitylate several target proteins including DDB1/DDB2, CDT1 (chromatin licensing and dna replication factor 1), DNA repair protein complementing XP-C cells (XPC), histone H2A, H3 and H4. In response to DNA damage Cul4A complex regulates protein stability of p53 and mouse double minute 2 homolog (MDM2)/ human double minute 2 homolog (HDM2).
