Identification and Characterization of a Phenyl(trifluoro-methyl)-pyrimidine Positive Allosteric Modulator of the Secretin Receptor [PDF]
MembranesG protein-coupled receptors (GPCRs) are among the most common drug targets, with numerous agonists and antagonists approved for clinical use. More recently, it has been appreciated that drugs can also modulate the action of natural agonists of these ...

Secretin targets interstitial cells of Cajal to regulate intestinal contractions [PDF]
EMBO ReportsSecretin is a gastrointestinal (GI) hormone that slows intestinal motility, an effect thought to be mediated through vagal afferent pathways. In this study we show evidence for a novel function of secretin involving a non-neural mechanism mediated by ...

Secretin-interacting plug proteins prevent antibiotic influx during type IV pilus assembly in Pseudomonas aeruginosa [PDF]
Nature CommunicationsType IV pili (T4P) are important virulence factors that mediate host attachment and other pathogenic functions. In Gram-negative bacteria, T4P are assembled from pilin subunits at the inner membrane (IM) and extend through the outer membrane (OM) via ...

Structural insights into the secretin complex of a type IVb pilus system [PDF]
Nature CommunicationsThe bundle-forming pilus (BFP) system in enteropathogenic Escherichia coli (EPEC) produces type IVb pili that enable bacterial auto-aggregation, facilitating bacterial adhesion, colonization, and virulence.

Origin of secretin receptor precedes the advent of tetrapoda: evidence on the separated origins of secretin and orexin. [PDF]
PLoS ONE, 2011 At present, secretin and its receptor have only been identified in mammals, and the origin of this ligand-receptor pair in early vertebrates is unclear.

A proform of secretin with high secretin‐like bioactivity [PDF]
FEBS Letters, 1985 A variant form of the heptacosapeptide amide secretin, with C‐terminal‐Val‐Gly‐Lys‐Arg instead of valine amide, has been isolated from porcine upper intestinal tissue. Unexpectedly, this triacontapeptide exhibited a substantially higher bioactivity than the heptacosapeptide amide.

Structure-Activity Relationship Studies of N- and C-Terminally Modified Secretin Analogs for the Human Secretin Receptor. [PDF]
PLoS ONE, 2016 The pleiotropic role of human secretin (hSCT) validates its potential use as a therapeutic agent. Nevertheless, the structure of secretin in complex with its receptor is necessary to develop a suitable therapeutic agent. Therefore, in an effort to design

Pleiotropic Effects of Secretin: A Potential Drug Candidate in the Treatment of Obesity?
Frontiers in Endocrinology, 2021 Secretin is the first hormone that has been discovered, inaugurating the era and the field of endocrinology. Despite the initial focus, the interest in its actions faded away over the decades. However, there is mounting evidence regarding the pleiotropic
