Introduction to Recombinant Human CUL4B Protein

Recombinant Human CUL4B Protein is a type of protein that is produced through genetic engineering techniques. This protein is a member of the Cullin family of proteins, which play a crucial role in the regulation of protein degradation and cell cycle progression. The CUL4B protein is encoded by the CUL4B gene and is involved in various cellular processes, including DNA replication, repair, and transcription. In this article, we will provide a scientific description of the structure, activity, and application of Recombinant Human CUL4B Protein.

Structure of Recombinant Human CUL4B Protein

The Recombinant Human CUL4B Protein is a 90 kDa protein that consists of 759 amino acids. It is composed of several domains, including a N-terminal domain, a C-terminal domain, and a central domain. The N-terminal domain contains a conserved BTB (Bric-a-brac, Tramtrack, and Broad-complex) domain, which is responsible for protein-protein interactions. The C-terminal domain contains a conserved Cullin homology domain, which is essential for the formation of the Cullin-RING E3 ubiquitin ligase complex. The central domain contains a WD40 repeat domain, which is involved in substrate recognition and binding.

Activity of Recombinant Human CUL4B Protein

Recombinant Human CUL4B Protein plays a crucial role in the regulation of protein degradation through the ubiquitin-proteasome pathway. It forms a complex with other proteins, including DDB1 (DNA damage-binding protein 1), RBX1 (RING-box protein 1), and DCAF (DDB1 and CUL4-associated factor) proteins, to form the Cullin-RING E3 ubiquitin ligase complex. This complex is involved in the transfer of ubiquitin molecules to target proteins, leading to their degradation by the proteasome.

In addition to its role in protein degradation, Recombinant Human CUL4B Protein is also involved in various cellular processes, including DNA replication, repair, and transcription. It has been shown to interact with several proteins involved in these processes, suggesting its role in their regulation.
