Semaphorin-4D/SEMA4D is the cell surface receptor for PLXNB1 and PLXNB2 and plays a crucial role in intercellular signaling.It regulates GABAergic synapse development and promotes inhibitory synapses in a PLXNB1-dependent manner.Semaphorin-4D/SEMA4D Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived Semaphorin-4D/SEMA4D protein, expressed by HEK293 , with C-hFc labeled tag.
