Interestingly, single alanine amino acid substitutions of some interacting residues within the TMD had much larger effects on exendin-4 affinity than removal of the first 8 residues of the peptide (exendin (939) 22,31 ), suggesting that peptide ECD and TMD interactions are correlated
Unlike GLS1, GLS2 is not inhibited by CB-839 or glutamate (its immediate byproduct), and can directly bind and inhibit Rac1 (Ras-related C3 botulinum toxin substrate 1), suppressing murine and human hepatocellular carcinoma cells migration and metastasis in a mouse model [205]
