Human Glial growth factor (GGF2) Recombinant

Recombinant human GGF2 (Glial growth factor) is a disulfide-linked monomeric protein consisting of 315 amino acid residues, and migrates as an approximately 34 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Neuregulin-1 isoform 9 (GGF2) was expressed inE. coli.

Product Specifications

Background

Neuregulins (NDF, heregulin, GGF, ARIA, or SMDF) are EGF-like growth and differentiation factors that signal through tyrosine kinase receptors of the ErbB family. The ErbB2 and ErbB4 receptors cooperate in transmission of neuregulin-1 signals in the heart, whereas ErbB2 and ErbB3 cooperate in neural crest cells.
