**Background of METTL7B Recombinant Protein**
METTL7B (Methyltransferase-like 7B) is a member of the methyltransferase superfamily, characterized by a conserved S-adenosylmethionine (SAM)-binding domain. While its precise biological role remains under investigation, METTL7B is hypothesized to catalyze methylation reactions, potentially targeting proteins, lipids, or nucleic acids. It is expressed in various tissues, including the liver, brain, and reproductive organs, suggesting involvement in diverse physiological processes.
Studies link METTL7B to lipid metabolism, cancer progression, and neurological functions. For instance, it is upregulated in hepatocellular carcinoma and may influence tumor cell proliferation. In the nervous system, METTL7B has been associated with neuronal differentiation and survival. However, its substrate specificity and regulatory mechanisms are not fully elucidated, highlighting the need for further research.
Recombinant METTL7B protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional and structural studies. This engineered protein retains enzymatic activity and is utilized to investigate METTL7B's interaction partners, methylation targets, and role in disease pathways. Its applications span *in vitro* assays, antibody development, and drug discovery, particularly for cancers or metabolic disorders linked to methylation dysregulation.
Current research focuses on clarifying METTL7B's substrate preferences, tissue-specific functions, and therapeutic potential. As a relatively understudied enzyme, METTL7B represents a compelling target for uncovering novel mechanisms in cellular regulation and disease.
