Anti-FGFR2/CD332 Antibody

Fibroblast growth factor receptor 2 (FGFR2) also known as CD332 has two naturally occurring isoforms FGFR2IIIb and FGFR2IIIc, created by splicing of the third immunoglobulin-like domain. FGFR2IIIb is predominantly found in ectoderm derived tissues and endothelial organ lining, i.e. skin and internal organs. FGFR2 has important roles in embryonic development and tissue repair, especially bone and blood vessels. Like the other members of the Fibroblast growth factor receptor family, these receptors signal by binding to their ligand and dimerisation (pairing of receptors), which causes the tyrosine kinase domains to initiate a cascade of intracellular signals. As mentioned, FGFR2 mutations are associated with craniosynostosis syndromes, which are skull malformations caused by premature fusion of cranial sutures and other disease features according to the mutation itself.
