Target data

See full target information Neurosecretory protein VGF

Function

Neurosecretory protein VGF. Secreted polyprotein that is packaged and proteolytically processed by prohormone convertases PCSK1 and PCSK2 in a cell-type-specific manner (By similarity). VGF and peptides derived from its processing play many roles in neurogenesis and neuroplasticity associated with learning, memory, depression and chronic pain (By similarity). Neuroendocrine regulatory peptide-1. Plays a role in the control of body fluid homeostasis by regulating vasopressin release. Suppresses presynaptic glutamatergic neurons connected to vasopressin neurons. Neuroendocrine regulatory peptide-2. 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 (By similarity). Stimulates also feeding behavior in an orexin-dependent manner in the hypothalamus (By similarity). Functions as a positive regulator for the activation of orexin neurons resulting in elevated gastric acid secretion and gastric emptying (By similarity). VGF-derived peptide TLQP-21. 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 (By similarity). Activates the G-protein-coupled receptor C3AR1 via a folding-upon-binding mechanism leading to enhanced lipolysis in adipocytes (By similarity). Interacts with C1QBP receptor in macrophages and microglia causing increased levels of intracellular calcium and hypersensitivity (By similarity). VGF-derived peptide TLQP-62. 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 (By similarity). Induces also insulin secretion in insulinoma cells by increasing intracellular calcium mobilization (By similarity). Antimicrobial peptide VGF[554-577]. Has bactericidal activity against M. luteus, and antifungal activity against P. Pastoris.

Activity summary

VGF also known as non-acronymic VGF is a neuropeptide precursor protein with a molecular mass approximately 68 kDa. It is expressed in neuroendocrine and neuronal tissues including the brain spinal cord and peripheral nervous system. VGF is synthesized as a large precursor and subsequently processed into smaller bioactive peptides with a variety of functions. The distribution and processing of VGF peptides suggest its diverse roles across different physiological contexts.

Biological function summary

VGF-derived peptides exert significant influence on energy balance neurogenesis and synaptic plasticity. These peptides participate in the regulation of appetite and energy expenditure contributing to body weight management. They are also involved in nerve growth and repair mechanisms. VGF peptides act independently or in conjunction with other neuropeptides and factors within the nervous system though it does not form a stable complex with other proteins.

Pathways

Few proteins have as diverse involvement as VGF in the neuroendocrine system's regulation. VGF links to the neurotrophic signaling pathway which promotes neuronal survival and growth. It shows interactions with proteins such as Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF) which support cellular health and energy homeostasis. VGF's role assists in the modulation of these pathways facilitating communication between energy state signals and neuronal networks.

Associated diseases and disorders

Alterations in VGF expression have implications in neurodegenerative diseases and mood disorders. Reduced levels of VGF peptides associate with Alzheimer's disease affecting cognitive functions and synaptic integrity. Additionally VGF influences in mood regulatory pathways relate it to major depressive disorder potentially interacting with proteins like the serotonin transporter which modulates mood and stress responses. Understanding VGF and its pathways can inform therapeutic strategies for these conditions.
