Sulfonylurea Receptor 1–Transient Receptor Potential Melastatin 4 Channel (SUR1-TRPM4)

Target
SUR1-TRPM4
Molecular classification
Ion channel, ATP-binding cassette (ABC) protein, Transient receptor potential (TRP) channel, Heteromeric ion channel complex
01

Overview

The Sulfonylurea Receptor 1–Transient Receptor Potential Melastatin 4 Channel (SUR1–TRPM4) is an inducible nonselective cation channel implicated primarily in pathological responses following central nervous system injury. Its unique molecular composition confers both biophysical properties from TRPM4 and drug sensitivity from SUR1—making it an important target for therapeutic intervention aimed at limiting secondary neuronal damage after acute insults.
