Background: Semaphorin 4A

Semaphorin 4A (Sema4A, previously semB) is type I transmembrane protein that is a Class 4 transmembrane Semaphorin with activity in the immune and nervous systems. It is expressed by dendritic cells, monocytes, T cells, B cells, astrocytes and oligodendrocytes, plus visceral smooth muscle and bronchial epithelial cells. The 760 amino acid (aa) mouse Sema4A contains a 650 aa extracellular domain (ECD, aa 33-682) with Sema, PSI and C2-type immunoglobulin domains. It interacts with B and D1 Plexins and lymphocyte TIM-2, enhancing dendritic cell-mediated T cell priming and Th1 responses. Sema4A interaction with endothelial cell plexin-D1 downregulates the actions of VEGF. Mutations of Sema4A are associated with retinitis pigmentosa and cone rod dystrophy in humans. Mouse Sema4A ECD shares 87% and 94% aa sequence identity with human and rat Sema4A, respectively, and shares approximately 35% aa identity with other Sema4 family members. Using this antibody, Sema4A has been shown to interact with Neuropilin-1 in vitro and in vivo to potentiate Treg cell function and survival.
