Target type: biologicalprocess
Any process that stops, prevents, or reduces the frequency, rate or extent of chemical reactions and pathways involving a protein. [GOC:ai]
Negative regulation of protein metabolic process involves a complex interplay of cellular mechanisms that control the production, modification, degradation, and localization of proteins. It ensures that protein levels are maintained within a specific range, preventing excessive protein synthesis or degradation. This tight control is crucial for maintaining cellular homeostasis, responding to environmental changes, and executing specific cellular functions.
Key aspects of this process include:
1. **Transcriptional Regulation:** Genes encoding proteins can be activated or repressed through the binding of transcription factors to DNA. This regulates the synthesis of mRNA, which serves as a template for protein production.
2. **Translational Regulation:** Translation, the process of converting mRNA into proteins, can be controlled by factors that influence the initiation, elongation, and termination of protein synthesis. This includes regulation of ribosome activity, mRNA stability, and microRNA interactions.
3. **Post-Translational Modification:** Proteins can undergo various modifications after translation, including phosphorylation, acetylation, ubiquitination, and glycosylation. These modifications can alter protein activity, stability, localization, and interactions with other molecules.
4. **Protein Degradation:** Unnecessary or damaged proteins are targeted for degradation through specific pathways. The ubiquitin-proteasome system is a major mechanism for protein degradation, where proteins are tagged with ubiquitin and subsequently broken down by proteasomes.
5. **Protein Localization:** The distribution of proteins within the cell is precisely regulated. Signals within proteins guide their trafficking to specific cellular compartments, ensuring their proper function.
Regulation of protein metabolism involves intricate feedback loops and signaling pathways, allowing cells to respond to environmental cues and internal stimuli. This intricate control system ensures that proteins are produced, modified, and degraded in a timely and precise manner, maintaining cellular function and survival.'

| clozapine | clozapine : 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.
