Recombinant Human RIOK3 Protein, N-His

The Structure of Recombinant Human RIOK3 Protein

Recombinant Human RIOK3 Protein is a highly conserved protein that belongs to the RIO kinase family. It is encoded by the RIOK3 gene and is also known as RIOK3, RIO3, or Rio3p. The protein is composed of 444 amino acids and has a molecular weight of approximately 50 kDa.

The structure of Recombinant Human RIOK3 Protein is characterized by a N-terminal kinase domain and a C-terminal domain. The kinase domain contains the catalytic site responsible for the protein’s kinase activity, while the C-terminal domain is involved in protein-protein interactions. The protein also has several conserved motifs, including a Walker A motif, a Walker B motif, and a P-loop motif, which are important for ATP binding and catalysis.

Recombinant Human RIOK3 Protein is a dimer in its active form, with each monomer containing the kinase and C-terminal domains. The dimerization of the protein is essential for its activity and stability.

The Activity of Recombinant Human RIOK3 Protein

Recombinant Human RIOK3 Protein is a serine/threonine protein kinase that plays a crucial role in various cellular processes, including cell cycle progression, ribosome biogenesis, and DNA damage response. It is involved in the phosphorylation of target proteins, which regulates their function and activity.

The main function of Recombinant Human RIOK3 Protein is its role in ribosome biogenesis. It is an essential component of the RIO kinase complex, which is responsible for the processing of 18S ribosomal RNA and the maturation of the 40S ribosomal subunit. This process is critical for the production of functional ribosomes and protein synthesis.

Additionally, Recombinant Human RIOK3 Protein is involved in the regulation of the cell cycle. It interacts with the tumor suppressor protein p53 and phosphorylates it, leading to its activation and subsequent cell cycle arrest. This activity is crucial for maintaining genomic stability and preventing the development of cancer.

The protein also plays a role in DNA damage response by phosphorylating histone H2AX, which is involved in the repair of DNA double-strand breaks. This activity is essential for maintaining the integrity of the genome and preventing mutations that can lead to diseases such as cancer.
