alpha1-adrenergic receptor activity

Definition

Target type: molecularfunction

Combining with epinephrine or norepinephrine to initiate a change in cell activity via activation of a G protein, with pharmacological characteristics of alpha1-adrenergic receptors; the activity involves transmitting the signal to the Gq alpha subunit of a heterotrimeric G protein. [GOC:cb, GOC:mah, IUPHAR_GPCR:1274]

Alpha1-adrenergic receptor activity is a molecular function associated with G protein-coupled receptors (GPCRs) that are activated by the neurotransmitter norepinephrine (noradrenaline) and epinephrine (adrenaline). These receptors play crucial roles in various physiological processes, including vasoconstriction, smooth muscle contraction, and regulation of heart rate and blood pressure.

Upon binding of norepinephrine or epinephrine to the alpha1-adrenergic receptor, a conformational change occurs in the receptor protein, triggering a cascade of intracellular signaling events. This cascade involves the activation of heterotrimeric G proteins, specifically the Gq/11 subtype.

The activated Gq/11 protein then stimulates the enzyme phospholipase C (PLC), which hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) into diacylglycerol (DAG) and inositol trisphosphate (IP3).

DAG activates protein kinase C (PKC), leading to phosphorylation of various downstream target proteins involved in cellular responses.

IP3, on the other hand, binds to IP3 receptors on the endoplasmic reticulum (ER), triggering the release of calcium ions (Ca2+) into the cytoplasm. The increase in intracellular calcium concentration activates various calcium-dependent signaling pathways, contributing to the physiological effects of alpha1-adrenergic receptor activation.

Overall, alpha1-adrenergic receptor activity initiates a complex intracellular signaling cascade, ultimately leading to diverse physiological responses, including smooth muscle contraction, vasoconstriction, and regulation of heart rate and blood pressure.'

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
