Semaphorin-5A/SEMA5A proteins act as bifunctional axon guidance signals, exerting attraction via heparan sulfate proteoglycans and inhibitory effects via chondroitin sulfate proteoglycans. As a ligand for the PLXNB3 receptor, SEMA5A disrupts glioma cell migration and invasion and induces cell collapse. Semaphorin-5A/SEMA5A Protein, Human (HEK293, His) is the recombinant human-derived Semaphorin-5A/SEMA5A protein, expressed by HEK293 , with C-6*His labeled tag.
