ACTH mechanism of action Corticotropin-like intermediate peptide (CLIP), also known as adrenocorticotropic hormone fragment 18-39 (ACTH(18-39)), is a biologically active peptide derived from the proteolytic cleavage of pro-opiomelanocortin (POMC)作者：JB Marshall·1984·被引用次数：30—We demonstrated thatCLIP stimulates amylase and protein secretionin a dose-dependent manner and is of similar potency to secretin and carbamylcholine.. This peptide, a significant component of the POMC hormone family, plays a role in various physiological processes, though its exact functions are still a subject of research. CLIP is primarily found in the intermediate lobe of the pituitary gland, but it has also been identified in central nerves and other endocrine cells.Short Communication: Identification of equine corticotropin- ... Understanding CLIP involves recognizing its origins within POMC, its structural relationship to ACTH, and its potential biological activities.Corticotropin-Like Intermediate Lobe Peptide MeSH ...
Pro-opiomelanocortin (POMC) is a large precursor protein that undergoes extensive post-translational processing to yield several biologically active peptides, including adrenocorticotropic hormone (ACTH), melanocyte-stimulating hormone (MSH), and beta-endorphin. CLIP is generated as a fragment during this cleavage process, specifically representing the amino acid sequence from position 18 to 39 of ACTH. This means CLIP is essentially a distinct segment of the larger ACTH molecule. Its chemical identity is often referred to as ACTH(18-39), highlighting its direct linkage to ACTH.
The primary site of CLIP production and localization is the intermediate lobe of the pituitary glandThe microtiter plate provided in this kit has been pre-coated withCorticotropin Like Intermediate Lobe Peptide(CLIP) protein. Standards or samples are added to .... This gland is a crucial component of the endocrine system, regulating many bodily functions through hormone secretionCLIP, orcorticotropin-like intermediate peptide, is defined as one of the peptides generated through the proteolytic cleavage of pro-opiomelanocortin (POMC), .... However, research has also revealed the presence of corticotropin-like peptides, including CLIP, in extra-pituitary locations. These include the central nervous system, where they may act as neurotransmitters or neuromodulators, and in gastrointestinal and pancreatic endocrine cells, suggesting broader roles beyond the pituitary.Effect of corticotropin-like intermediate lobe peptide on ...
While CLIP is a well-defined peptide, its precise physiological functions are less established compared to other POMC-derived peptides like ACTH. Early research has indicated that CLIP can stimulate amylase and protein secretion from the pancreas in a dose-dependent manner, with a potency comparable to other known secretagogues like secretin and carbamylcholineCorticotropin - an overview | ScienceDirect Topics. This suggests a potential role in digestive processes.
Furthermore, some studies have explored the effects of CLIP and its fragments on sleep architecture, with findings suggesting an increase in paradoxical sleep. There is also evidence hinting at CLIP acting as an insulin secretagogue, meaning it could influence insulin release from the pancreas, though this requires further investigation. The broader context of POMC processing also links CLIP to the stress response axis, as ACTH itself is a key hormone in this pathway, released in response to corticotropin-releasing hormone (CRH) and arginine vasopressin (AVP)2025年11月9日—In a previous study, seasonally-dependent assay cross-reactivity to endogenous equinecorticotropin-like intermediatelobepeptide(CLIP,ACTH.... While CLIP is a fragment of ACTH, its specific contribution to the stress response or its interaction with this axis is an area of ongoing scientific inquiry.
The study of CLIP has been facilitated by the development of specific assays, such as ELISA kits designed for the quantitative measurement of human Corticotropin Like Intermediate Lobe Peptide (CLIP). These kits are valuable tools for researchers investigating the role of CLIP in various physiological and pathological conditions.Corticotropin-Like Intermediate Lobe Peptide MeSH ... For instance, studies have examined equine corticotropin-like intermediate lobe peptide to understand its presence and potential cross-reactivity in animal models, which can inform research on related conditions in other species. The chemical synthesis of CLIP has also been achieved, allowing for more controlled experimental manipulations and a deeper understanding of its propertiesACTH (18-39), human [53917-42-3] quantity. 0.00.

Corticotropin-like intermediate peptide (CLIP) represents a fascinating fragment of the POMC precursor molecule, sharing a direct structural lineage with ACTH作者：SL Wardlaw·1986·被引用次数：65—Ovarian steroids have previously been shown to regulate the hypothalamic content of beta-endorphin (beta EP) and its release into hypophyseal portal blood.. While its primary residence is the pituitary intermediate lobe, its detection in other neural and endocrine tissues points to a potentially diverse range of biological roles. Although research into its specific functions, such as its influence on pancreatic secretion and potential effects on sleep and insulin regulation, is ongoing, CLIP remains an important peptide for scientific exploration within the broader POMC family and the neuroendocrine system.
