Buy FGL online | FGL for sale

FGL peptide is a synthetic 15–amino acid peptide fragment derived from a functional region associated with Fibroblast Growth Factor-2 (FGF-2) signaling. The peptide corresponds to a sequence that mimics the FG loop region of the Neural Cell Adhesion Molecule (NCAM), a protein involved in cellular communication within neural tissues.

Because of this structural relationship, FGL is frequently studied in investigational neuroscience research to explore mechanisms related to receptor-mediated signaling and neuronal communication.

In in vitro studies and experimental research models, FGL is used to investigate how NCAM-associated peptide fragments interact with fibroblast growth factor receptors (FGFRs) and influence intracellular signaling pathways. These molecular interactions are of interest in laboratory environments examining synaptic signaling networks, receptor activation mechanisms, and intracellular signal transduction processes.

Chemical Structure Description

Working Mechanism

FGL peptide is investigated in experimental neuroscience models for its ability to mimic a functional interaction region associated with NCAM-FGFR signaling. The mechanism examined in laboratory studies primarily involves receptor activation and intracellular signal transduction pathways.

FGL contains a sequence designed to replicate a region of NCAM responsible for interaction with fibroblast growth factor receptor-1 (FGFR1).
When studied in experimental cell systems, FGL can bind to FGFR1, a receptor tyrosine kinase associated with multiple intracellular signaling cascades.
Through receptor-mediated signaling activation, FGL is investigated as a research tool for studying intracellular pathways involved in neuronal signaling processes, synaptic communication mechanisms, and receptor-driven transcriptional responses within controlled experimental systems.

Experimental studies have shown that FGFR1 activation can trigger several intracellular pathways frequently examined in cell signaling research, including:

MAPK/ERK signaling pathway, involved in cellular signal transduction and transcriptional regulation
PI3K–Akt signaling pathway, associated with intracellular regulatory signaling networks
PLCγ pathway, which contributes to intracellular calcium signaling dynamics
