GtoPdb Ligand ID: 13915

Compound class: Antibody
Comment: Nb23-bi is a bivalent nanobody that targets an allosteric domain within the N terminal region of adhesion GPCR ADGRG2 [1]. Nanobody binding induces conformational changes in orthosteric DHEA binding site that promote DHEA induced receptor activation. Nb23-bi reverses the dysfunctions (e.g. orchitis and infertility) caused by gain-of-function ADGRG2 mutants in vivo.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.
