Secretogranin III (SCG3) is a member of the granin family of acidic secretory proteins, which includes chromogranins and secretogranins. These proteins are predominantly expressed in neuroendocrine and endocrine cells, where they play critical roles in the biogenesis, sorting, and regulated secretion of peptide hormones and neurotransmitters. SCG3 is synthesized as a precursor protein and processed into smaller bioactive peptides within secretory granules. It is known to interact with other granins, such as chromogranin A, and contributes to the stabilization of secretory granule membranes, as well as the modulation of hormone storage and release.
SCG3 has garnered attention due to its tissue-specific expression and potential involvement in various physiological and pathological processes. Studies suggest its role in regulating glucose metabolism, cardiovascular function, and stress responses. Notably, SCG3 is highly expressed in pancreatic islets, adrenal glands, and the central nervous system, implicating its importance in endocrine and neuroendocrine signaling. Emerging research also links SCG3 to diseases such as diabetes, hypertension, and cancer, where its dysregulation may influence tumor angiogenesis or neuroendocrine tumor progression.
Recombinant SCG3 protein, produced through heterologous expression systems like mammalian or bacterial cells, enables researchers to study its structural and functional properties in vitro. This tool has been instrumental in investigating SCG3's interactions with cellular receptors, its proteolytic processing, and its potential as a biomarker or therapeutic target. By providing a purified and scalable source of the protein, recombinant SCG3 facilitates mechanistic studies and drug discovery efforts aimed at modulating secretory pathways or addressing granin-related disorders.
