Side-by-Side Comparison
About FGL
Mimics NCAM-mediated signaling via FGFR (fibroblast growth factor receptor) activation. Stimulates downstream Erk1/2 and PLCγ pathways. Promotes long-term potentiation (LTP) and synaptogenesis.
A peptide derived from the fibronectin type III (FGL) module of neural cell adhesion molecule (NCAM). Promotes synaptic plasticity, memory formation, and neuroprotection in preclinical models by mimicking NCAM-mediated signaling.
