GtoPdb Ligand ID: 11080

Synonyms: tat-M2NX
Compound class: Peptide
Comment: TatM2NX is a cell permeable peptide-inhibitor (antagonist) of the transient receptor potential melastatin 2 (TRPM2) ion channel [1]. The M2NX portion of the peptide targets the Nudix motif ADP ribose binding site at the C-terminal of the TRPM2 channel and the N terminus tat-human immunodeficiency virus (HIV) sequence YGRKKRRQRRR mediates cell permeability. TatM2NX can be used as a tool to study TRPM2's role in brain physiology and pathophysiology, and its clinical potential as a novel neuroprotective target for the treatment of neurological diseases.

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.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.
