NCIt definition : Probetacellulin (178 aa, 20 kDa) is encoded by the human BTC gene. This protein plays
a role in cellular proliferation.;
NCIt note : The active form of the growth factor, called betacellulin, is produced by proteolytic
cleavage that removes 67 amino acids from the C-terminus of probetacellulin. The precursor
is a type I membrane protein and the mature form is a secreted protein. (UniProt);
