Recombinant Human SEMA3A Protein (Fc Tag)
Product Specifications
Background
This gene is a member of the semaphorin family and encodes a protein with an Ig-like C2-type (immunoglobulin-like) domain, a PSI domain and a Sema domain. This secreted protein can function as either a chemorepulsive agent, inhibiting axonal outgrowth, or as a chemoattractive agent, stimulating the growth of apical dendrites. In both cases, the protein is vital for normal neuronal pattern development. Increased expression of this protein is associated with an schizophrenia and is seen in a variety of human tumor cell lines. Also, aberrant release of this protein is associated with an the progression of Alzheimer's disease.
