Influence of protein SGIP1 on partners participating in signalization of cannabinoid receptor 1
 Pejšková, Lucie ; Blahoš, Jaroslav (advisor) ; Novotný, Jiří (referee)
The G-protein-coupled receptor (GPCR) family represents the largest family of cell surface receptors. GPCRs are activated by endogenous or exogenous ligands, and are targets for more than a quarter of currently used drugs. Activation of receptors initiates intracellular signaling pathways. This way the membrane receptors transfer information from the outside environment into the cell. Based on the signal the cell can respond to the changes of the environment. Key observation important for this thesis is interplay of cannabinoid and opioid signaling in vivo, which can have significant physiological effects1 . Cannabinoid receptor 1 (CB1R) and µ opioid receptor (MOR) belong to the rhodopsin family of receptors, and both are coupled with Gαi/o proteins2 . Both are located in certain areas in central nervous system (CNS) and share a lot of important features. Activation of both of the receptors leads to inhibition of adenylyl cyclase, thus decreasing the level of cyclic adenosine monophosphate in the cell, and modulates extracellular regulated kinase 1 and 2 (ERK1/2)2 . In view of the numerous anatomical, biochemical and pharmacological evidence supporting the existence of the functional interaction between opioid3 and cannabinoid receptor systems this topic became interesting for our research. In our...
