NCIt definition : Proepiregulin (169 aa, 19 kDa) is encoded by the human EREG gene. This protein plays
a role in the promotion of cell proliferation.;
NCIt note : The active form of the growth factor, epiregulin, is produced by two proteolytic cleavage
events that remove 59 N-terminal amino acids and 61 amino acids from the C-terminus
of proepiregulin. The precursor is a type I membrane protein and the mature form is
a secreted protein. (UniProt);
