Formyl peptide receptor 2 - an emerging modulator of inflammation in the liver

Published on March 6th 2023

Formyl peptide receptors (FPRs) are seven-membrane G-protein coupled receptors whichrecognize chemotactic signals to protect hosts from pathogenic infections and mediate inflammatory responses in the body. There are three isoforms of FPRs in humans—FPR1, FPR2, and FPR3—and they bind to N-formyl peptides, except FPR3, and to various endogenous agonists. Among FPR family members, FPR2 has a lower affinity for N-formyl peptides than FPR1 and binds with a wide range of endogenous or exogenous ag...

Transient receptor potential (TRP) channel modulators

Published on August 4th 2022

Transient receptor potential (TRP) channels are a superfamily of cation channels that is currently subdivided into nine families split into two groups, each containing a number of subfamilies. TRP channels are expressed ubiquitously and are activated by a wide range of stimuli.TRP subunits assemble into homo- or heterotetramers and are often functionally associated with G-protein-coupled receptors, receptor tyrosine kinases and phospholipase C. As TRPs are intimately linked with intracellular Ca...

Sortase reagents

Published on November 4th 2021

Protein-sorting transpeptidases are enzymes that cleave target proteins produced by the same cell, as part of a specialized pathway of protein targeting. Protein-sorting transpeptidases transferthe N-terminal portion of the cleaved polypeptide into another molecule. The term sortase is correctly reserved for the cysteine protease enzymes sortase A, sortase B, and members of additional classes, all of which share homology. We now offer the sortase recognition sequence, LPETGG, coupled to the flu...

Orexin receptor peptides

Published on October 18th 2021

Orexins (hypocretins) are a family of neuropeptides consisting of two members, orexin A and orexin B, which are produced from a common precursor prepro-orexin. The orexins activate two G-protein-coupled receptors (OX1 and OX2), bothfound predominantly in the hypothalamus. Orexin A is the selective endogenous agonist for OX1 and blocking this receptor modulates food and water intake. Orexins are also linked to the regulation of sleep-activity cycles.

New range of PAR receptor ligands

Published on August 10th 2021

Protease-activated receptors (PARs, also known as thrombin receptors) are G-protein-coupled receptors which are activated by cleavage of their N-terminal domains by serine proteases. Cleavage produces a tethered peptide ligand, which influences transmembrane signaling. Four subtypes of receptors been cloned (PAR1-4). PAR1 is the most well characterized member of this receptor family and is activated by the endogenous serine protease thrombin. PAR1 activation has been implicated in cardiovascu...
