Gene Information

human ... CUL4A(8451)

General description

Cullin-4A (UniProt Q13619; also known as CUL-4A) is encoded by the CUL4A gene (Gene ID 8451) in human. Polyubiquitination of proteins is mediated by ubiquitin-activating enzymes (E1s), ubiquitin-conjugating enzymes (E2s), and ubiquitin ligases (E3s). There exist RING finger-type (really interesting new gene), HECT-type (homologous to E6-AP C-terminus), and U-box type of E3 ligases. Cullin-4 belongs to the cullin family of hydrophobic proteins that confer substrate specificity to the multimeric Cullin-RING E3 ubiquitin ligase (CRL) complexes by acting as scaffold proteins. The human genome encodes 8 cullin proteins (CUL 1, 2, 3, 4A, 4B, 5, 7 and 9). The activity of CRLs is regulated by Cullin Neddylation via the reversible conjugation of a small ubiquitin-type protein known as Neural precursor cell expressed developmentally down-regulated protein 8 (Nedd8). CUL4A interacts with the substrate-binding adaptor DDB1 (DNA damage binding protein 1) via its arc-shaped helical N-terminal domain, and binds the small RING finger protein ROC1 (regulator of cullins 1) via its globular C-terminal domain. Despite the 83% sequence identity and seemingly functional redundancy between CUL4A and CUL4B, much more focus is placed on CUL4A in oncogenesis research.

Post-Translational Modifications
New Products Flyer- Vol 4 Signaling Feature- NEW! Phosphohistidine Antibody

"Mods – modifications – small alterations can have a big impact on form and function. In the motorsports world, stock vehicles are modified to enhance their performance. Modifications, or mods, to the engine, drive train, intake and exhaust components add up to provide phenomenal performance gains that can be measured as horsepower and torque increases, which yield a competitive advantage, and result in reduced run times. In biology, proteins undergo modifications that alter their function. Some proteins require the modifications in order to perform their function effectively, whether it’s a pro-protein that is cleaved to produce an active enzyme, or a protein that is phosphorylated to facilitate a signaling process. Other proteins, such as histones, undergo modifications that regulate gene expression and alter cellular function. There are several post translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination that impact protein function and activity. As a result, the analysis of proteins and their post-translational modifications are particularly important for the study of normal and disease-associated processes. New antibodies to detect phospho Histidines are now available from EMD Millipore."
