产品介绍
g-基丁酸(GABA)是哺乳动物中枢神经系统中重要的抑制性神经递质，在体内通过作用于离子通道型的GABAA、GABAC受体及代谢型的GABAB受体而发挥生理功能。
GABAB1受体存在于神经元的突触前及突触后部位，介导慢的抑制性效应，在脑内参与许多重要的生理活动和病理变化，包括认知损害、癫痫、痉挛及药物成瘾等。GABAB受体属于G蛋白偶联受体家族的C家族，具有七次跨膜结构，N-端位于胞外，C-端位于胞内。
Receptor for GABA. The activity of this receptor is mediated by G-proteins that inhibit adenylyl cyclase activity, stimulates phospholipase A2, activates potassium channels, inactivates voltage-dependent calcium-channels and modulates inositol phospholipids hydrolysis. Plays a critical role in the fine-tuning of inhibitory synaptic transmission. Pre-synaptic GABA-B-R inhibit neurotransmitter release by down-regulating high-voltage activated calcium channels, whereas postsynaptic GABA-B-R decrease neuronal excitability by activating a prominent inwardly rectifying potassium (Kir) conductance that underlies the late inhibitory postsynaptic potentials. Not only implicated in synaptic inhibition but also in hippocampal long-term potentiation, slow wave sleep, muscle relaxation and antinociception. Activated by (-)-baclofen, cgp27492 and blocked by phaclofen.
[FUNCTION] Isoform 1E function may be to regulate the availability of functional GABA-B-R1A/GABA-B-R2 heterodimers by competing for GABA-B-R2 dimerization. This could explain the observation that certain small molecule ligands exhibit differential affinity for central versus peripheral sites. Subcellular location at Cell membrane; Multi-pass membrane protein. Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein.
[TISSUE SPECIFICITY] Highly expressed in brain and weakly in heart, Belongs to the G-protein coupled receptor 3 family. GABA-B receptor subfamily.
