Applicazioni

Glycerol kinase (glpK) was used to study the effects of pain controlling neuropeptides on human fat cell lipolysis.

Azioni biochim/fisiol

Glycerol kinase catalyzes tge MgATP-dependent phosphorylation of glycerol to produce sn-glycerol-3-phosphate and is the rate limiting enzyme in the utilization of glycerol. It is also subject to feedback regulation by fructose-1,6-bisphosphate.

Neuropeptides NPFF and NPSF are involved in pain control, acting through the G-protein coupled receptors (GPR)74 (high affinity for NPFF) and GPR147 (equal affinity for NPFF and NPSF). GPR74 also inhibits catecholamine-induced adipocyte lipolysis and regulates fat mass in humans.
