Human Semaphorin 4A/SEMA4A Ig-like Domain Protein (SEM-HM2D3) Summary

Product Description

Recombinant Human Semaphorin 4A/SEMA4A Ig-like Domain Protein is expressed from HEK293 with hFc (IgG1) tag at the C-terminus.It contains Asn573-Phe631.

Product Background

Neuroimmune semaphorin 4A (Sema4A), a member of semaphorin family of transmembrane and secreted proteins, is an important regulator of neuronal and immune functions. In the nervous system, Sema4A primarily regulates the functional activity of neurons serving as an axon guidance molecule. In the immune system, Sema4A regulates immune cell activation and function, instructing a fine tuning of the immune response.
