Recombinant human GPR142 protein is a genetically engineered form of the G protein-coupled receptor 142 (GPR142), a class of cell surface receptors implicated in metabolic regulation and nutrient sensing. GPR142. primarily expressed in pancreatic β-cells, enteroendocrine cells, and specific brain regions, is thought to play a role in modulating insulin secretion, glucose homeostasis, and appetite regulation. Although its endogenous ligands remain under investigation, studies suggest potential interactions with aromatic amino acids (e.g., tryptophan) or metabolites, triggering downstream signaling pathways such as cAMP or calcium mobilization.
The recombinant protein is produced using heterologous expression systems like mammalian cells (e.g., HEK293) or insect cells to ensure proper post-translational modifications and functional activity. Its production enables detailed biochemical and pharmacological studies, including ligand binding assays, receptor activation profiling, and structural analyses. GPR142 has garnered interest as a therapeutic target for metabolic disorders, particularly type 2 diabetes and obesity, due to its influence on insulin secretion and gut-brain signaling. However, its physiological role remains partially elusive, necessitating further research to clarify signaling mechanisms and pathophysiological relevance. Recombinant GPR142 tools are critical for developing high-throughput screening platforms to identify agonists or antagonists for drug discovery.
