GoKawiilResearchers identify 'superdark' protein resembling a GPCR with atypical signaling behavior
Scientists have discovered a protein, nicknamed 'superdark' for its poorly characterized status, that structurally resembles a G-protein-coupled receptor (GPCR) but does not behave like typical members of this receptor family. The finding suggests the protein may represent an unusual or previously unrecognized branch of GPCR-like signaling molecules.
