Recombinant human Neuregulin 1 (NRG1) is expressed in CHO cells to ensure proper folding and authentic mammalian post-translational modifications. This tag-free protein retains the native structure and high bioactivity of human NRG1, making it suitable for diverse applications in cell signaling and neurobiology research.

NRG1 is a growth and differentiation factor involved in the regulation of cell-cell communication, particularly in the nervous and cardiovascular systems. It plays critical roles in neural development, synapse formation, and cardiac function by activating ErbB receptor tyrosine kinases. Recombinant human NRG1 is widely used in studies of neurodevelopment, cardiac biology, and receptor signaling pathways.
