Recombinant Proteins
Recombinant Human CUL4A Protein is a highly versatile protein that has gained immense popularity in the field of biotechnology and medical research. It is a recombinant protein, meaning it is produced through genetic engineering techniques, and is derived from the human CUL4A gene. This protein plays a crucial role in various cellular processes and has a wide range of applications in both basic research and therapeutic development.
The recombinant human CUL4A protein is a 91 kDa protein composed of 759 amino acids. It belongs to the Cullin family of proteins and is characterized by a conserved C-terminal domain known as the Cullin homology domain (CHD). This domain is responsible for the interaction with other proteins, specifically the substrate receptor proteins, to form the Cullin-RING E3 ligase complex. The N-terminal of the CUL4A protein contains a leucine-rich repeat (LRR) domain, which is involved in protein-protein interactions and plays a crucial role in the regulation of the protein’s activity.
The CUL4A protein also has a highly conserved NEDD8 modification site, which is essential for the proper functioning of the protein. This site allows for the attachment of the small ubiquitin-like modifier (SUMO) protein, which regulates the activity of the CUL4A protein by promoting its interaction with other proteins.
The primary function of the CUL4A protein is to act as a scaffold protein in the Cullin-RING E3 ligase complex. This complex is responsible for the ubiquitination and subsequent degradation of target proteins, thereby regulating various cellular processes such as cell cycle progression, DNA damage response, and protein turnover.
The CUL4A protein plays a crucial role in maintaining genomic stability by regulating the cell cycle and DNA repair mechanisms. It is also involved in the regulation of transcription and chromatin remodeling, making it a key player in gene expression control. Additionally, the CUL4A protein has been found to be involved in the regulation of cell proliferation, differentiation, and apoptosis.
The unique structure and versatile activity of the recombinant human CUL4A protein make it a valuable tool in various fields of research and development. Some of the key applications of this protein include:
The CUL4A protein is involved in multiple protein-protein interactions, making it an ideal candidate for studying protein-protein interactions and their role in various cellular processes. Recombinant CUL4A protein can be used in pull-down assays and co-immunoprecipitation experiments to identify and characterize its interacting partners.
The CUL4A protein has been implicated in various diseases, including cancer, making it a potential target for drug development. Recombinant CUL4A protein can be used in high-throughput screening assays to identify small molecule inhibitors that can disrupt its activity and potentially be developed as targeted therapies for diseases associated with CUL4A dysregulation.
Recombinant human CUL4A protein can also be used in diagnostic applications, specifically in cancer diagnosis. Elevated levels of CUL4A protein have been observed in various types of cancer, and its detection in patient samples can serve as a potential biomarker for early detection and monitoring of the disease.
The CUL4A protein has been extensively studied, and its structure and activity have been well characterized. This makes it an ideal candidate for protein
