tokens: Coexpression of the p120 ( ctn ) protein with an N-terminal deletion , which eliminates some potential tyrosine phosphorylation sites , or the protein with a single amino acid substitution ( tyrosine at 217 to phenylalanine ) resulted in an increase in the aggregation of v-Src transformed EL and EalphaCL cells .
