SEM4G Rabbit Polyclonal Antibody

Semaphorins are a large family of conserved secreted and membrane associated proteins which possess a semaphorin (Sema) domain and a PSI domain (found in plexins| semaphorins and integrins) in the N-terminal extracellular portion. Based on sequence and structural similarities| semaphorins are put into eight classes: invertebrates contain classes 1 and 2| viruses have class V| and vertebrates contain classes 3-7. Semaphorins serve as axon guidance ligands via multimeric receptor complexes| some (if not all) containing plexin proteins. Multiple transcript variants encoding different isoforms have been found for this gene.
