NCIt definition : Protransforming growth factor alpha (160 aa, 17 kDa) is encoded by the human TGFA
gene. This protein plays a role in cell proliferation.;
NCIt note : The active form of the growth factor, transforming growth factor alpha, is produced
when proteolytic cleavage removes 39 amino acids from the N-terminus and 71 amino
acids from the C-terminus of protransforming growth factor alpha. The precursor is
a transmembrane protein and the mature form is a secreted protein. (UniProt);
