VGF

Target Full Name

Neurosecretory protein VGF

Target Function

Secreted polyprotein that is packaged and proteolytically processed by prohormone convertases PCSK1 and PCSK2 in a cell-type-specific manner. VGF and peptides derived from its processing play many roles in neurogenesis and neuroplasticity associated with learning, memory, depression and chronic pain.; Plays a role in the control of body fluid homeostasis by regulating vasopressin release. Suppresses presynaptic glutamatergic neurons connected to vasopressin neurons.; Plays a role in the control of body fluid homeostasis by regulating vasopressin release. Activates GABAergic interneurons which are inhibitory neurons of the nervous system and thereby suppresses presynaptic glutamatergic neurons. Stimulates also feeding behavior in an orexin-dependent manner in the hypothalamus. Functions as a positive regulator for the activation of orexin neurons resulting in elevated gastric acid secretion and gastric emptying.; Secreted multifunctional neuropeptide that binds to different cell receptors and thereby plays multiple physiological roles including modulation of energy expenditure, pain, response to stress, gastric regulation, glucose homeostasis as well as lipolysis. Activates the G-protein-coupled receptor C3AR1 via a folding-upon-binding mechanism leading to enhanced lipolysis in adipocytes. Interacts with C1QBP receptor in macrophages and microglia causing increased levels of intracellular calcium and hypersensitivity.; Plays a role in the regulation of memory formation and depression-related behaviors potentially by influencing synaptic plasticity and neurogenesis. Induces acute and transient activation of the NTRK2/TRKB receptor and subsequent CREB phosphorylation. Induces also insulin secretion in insulinoma cells by increasing intracellular calcium mobilization.; Has bactericidal activity against M. luteus, and antifungal activity against P. Pastoris.

Target Background

This gene is specifically expressed in a subpopulation of neuroendocrine cells, and is upregulated by nerve growth factor. The structural organization of this gene is similar to that of the rat gene, and both the translated and the untranslated regions show a high degree of sequence similarity to the rat gene. The encoded secretory protein also shares similarities with the secretogranin/chromogranin family, however, its exact function is not known.
