Signal Pathway


In some cases, receptor activation caused by ligand binding to a receptor is directly coupled to the cell's response to the ligand. For example, the neurotransmitter GABA can activate a cell surface receptor that is part of an ion channel. GABA binding to a GABAA receptor on a neuron opens a chloride-selective ion channel that is part of the receptor. GABAA receptor activation allows negatively charged chloride ions to move into the neuron, which inhibits the ability of the neuron to produce action potentials.

  • Nicotinamide EY0367

    Nicotinamide (NAM), an amide form of niacin (vitamin B3), is a water-soluble and noncompetitive inhibitor of the deacetylation reaction catalyzed by Sirtuins and it acts as constituent of the enzyme cofactors NAD and NADP. Nicotinamide (Vitamin B3) 是一种水溶性维生素，是NAD 和 NADP的活性成分，也是一种sirtuins抑制剂。
