Human NRG1-beta 1/HRG1-beta 1 EGF Domain Antibody Summary

Species Reactivity
Detects human NRG1-beta 1 in ELISAs. Recognizes an epitope found in the EGF-like domain of NRG1‑ beta 1 (amino acids 179‑246). It also detects recombinant human SMDF (Sensory and Motor neuron-Derived Factor), but it does not recognize the EGF-like domain of human NRG1-alpha (amino acids 177‑241). The epitope is present within amino acids 213‑230 of human NRG1-beta 1. This segment is present in all NRG1 beta isoforms, GGF‑2 (glial growth factor), and SMDF, but it is absent from NRG1-alpha, NDF43, and NRG1-gamma.

Background: Neuregulin-1 beta 1/NRG1 beta 1

Neuregulin-1, also known as Heregulin 1, functions as a ligand for the receptor tyrosine kinases, ErbB3 and ErbB4. It exists in several different mRNA splicing variants resulting in both transmembrane and secreted forms.
