Description

The chromogranins, secretogranins and additional related proteins that together comprise the granin family subserve essential roles in the regulated secretory pathway that is responsible for controlled delivery of peptides, hormones, neurotransmitters and growth factors. This course reviews the structure and function of granins and granin-derived peptides, and expansive new genetic evidence, including recent single nucleotide polymorphism (SNP) mapping, genomic sequence comparisons, and analysis of transgenic and knockout mice, which together support an important and evolutionarily conserved role for these proteins in large dense core vesicle biogenesis and regulated secretion. It also reviews recent data further indicating that their processed peptides function prominently in metabolic and glucose homeostasis, emotional behavior, pain pathways, and blood pressure modulation, suggesting future utility of granins and granin-derived peptides as novel disease biomarkers.
