Description of Recombinant Human ALKBH7 Protein, N-His

Introduction to Recombinant Human ALKBH7 Protein

Recombinant Human ALKBH7 Protein is a highly specialized protein that plays a crucial role in several biological processes in the human body. It is a member of the AlkB family of proteins, which are involved in DNA repair and modification. The ALKBH7 protein is encoded by the ALKBH7 gene and is found in both humans and mice.

Structure of Recombinant Human ALKBH7 Protein

The ALKBH7 protein is composed of 384 amino acids and has a molecular weight of 43 kDa. It contains a conserved catalytic domain, which is responsible for its enzymatic activity. This domain is known as the AlkB homologous domain and is found in all members of the AlkB family of proteins. The ALKBH7 protein also contains a nuclear localization signal, which allows it to be transported into the nucleus of the cell where it carries out its functions.

The crystal structure of the ALKBH7 protein has been determined, revealing that it is composed of two domains, the N-terminal and C-terminal domains, connected by a flexible linker. The N-terminal domain is responsible for DNA binding, while the C-terminal domain contains the catalytic site responsible for the protein’s enzymatic activity.

Enzymatic Activity of Recombinant Human ALKBH7 Protein

The ALKBH7 protein is a dioxygenase enzyme, which means it uses molecular oxygen to catalyze chemical reactions. Its main function is to remove alkyl groups from DNA, specifically from the nitrogen bases adenine and cytosine. These alkyl groups can be introduced into DNA by exposure to environmental toxins or as a result of normal cellular processes.

The ALKBH7 protein works by binding to the damaged DNA and using molecular oxygen to oxidize the alkyl group, converting it into a hydroxyl group. This process restores the integrity of the DNA and prevents mutations from occurring. The protein also has the ability to remove methyl groups from RNA, further expanding its role in maintaining the integrity of genetic material.

Application of Recombinant Human ALKBH7 Protein

The ALKBH7 protein has been found to play a critical role in several biological processes, making it a valuable tool for research and potential therapeutic applications. Some of its key applications include:

1. DNA Repair

The ALKBH7 protein’s ability to remove alkyl groups from DNA makes it an important player in DNA repair mechanisms. Defects in the ALKBH7 gene have been linked to increased susceptibility to DNA damage and cancer, highlighting the importance of this protein in maintaining genomic stability.

2. Epigenetic Regulation

The ALKBH7 protein has been shown to play a role in regulating epigenetic modifications, specifically in the removal of methyl groups from RNA. This process is crucial for gene expression and has implications in various diseases, including cancer and neurodegenerative disorders.

3. Potential Therapeutic Target

Due to its involvement in DNA repair and epigenetic regulation, the ALKBH7 protein has been identified as a potential therapeutic target. Modulating its activity could have implications in the treatment of various diseases, including cancer and neurological disorders.

4. Biomarker for Cancer Diagnosis

Recent studies have shown that the ALKBH7 protein is overexpressed in certain types of cancer, making it a potential biomarker for cancer diagnosis and prognosis. Its expression levels could also be used to monitor the response to cancer treatment.

5. Recombinant Protein Production

Recombinant Human ALKBH7 Protein is also used in the production of other recombinant proteins. It can be used as a fusion partner to improve the solubility and stability of other proteins,
