NCIt definition : Pro-neuregulin-1, membrane-bound isoform (640 aa, 70 kDa) is encoded by the human
NRG1 gene. This protein plays a role in tyrosine kinase receptor-mediated signal transduction.;
NCIt note : The active form of the growth factor, neuregulin-1, is produced by two proteolytic
cleavage events that remove the 19 N-terminal amino acid signal sequence and 399 amino
acids from the C-terminus of pro-neuregulin-1, membrane-bound isoform. The precursor
is a type I membrane protein and the mature form is a secreted protein. (UniProt);
