The molecular mechanisms N. meningitidis employ to manipulate the immune system, translocate the mucosal Human-associated bacteria encode a variety of bioactive small molecules with growing evidence for N-acyl Here, we heterologously expressed an N-acyltransferase encoded in the obligate human pathogen N. meningitidis and identified 30 N-acyl amides with representative members serving as agonists of the G-protein coupled During this process, we also characterized two mammalian N-acyl amides derived from the bovine medium

October 2022 N-terminal alterations turn the gut hormone GLP-2 into an antagonist with gradual loss of Searching for antagonist activity, we performed systematic N-terminal truncations of human GLP-2(1-33

September 2022 Isoforms of GPR35 have distinct extracellular N-termini that allosterically modify receptor-transducer known to be expressed as two distinct isoforms that differ only in the length of their extracellular N-termini Our results reveal that the extended N-terminus of the long isoform limits G protein activation yet elevates We found that a proposed disulfide bridge between the N-terminus and extracellular loop 3, present in is crucial for constitutive G13 activation, while an additional cysteine contributed by the extended N-terminus

< GPCR News < GPCRs in Oncology and Immunology Chemokine N-terminal-derived peptides differentially regulate MIP chemokines, such as CCL3 and CCL5 are processed at the N-terminus, which influences signaling in Here, we investigate the signaling capacity of peptides corresponding to truncated N-termini. In conclusion, chemokine N-termini can be mimicked to produce small CCR1-selective agonists, as well

Oncology and Immunology Stable Binding of Full-Length Chemerin is Driven by Negative Charges in the CMKLR1 N-terminus Here, we demonstrate that negative charges in the CMKLR1 N-terminus are involved in the formation of
