to determine whether this was true for the human epidermal growth factor ( egf ) receptor , which is also a membrane-associated tyrosine kinase proto-oncogene , we have constructed two premature termination mutants , dc19 and dc63 , that delete the c-terminal 19 and 63 amino acids , respectively , from the human full-length receptor ( hegfr ) .
