Major substrate for growth factor-activated protein-tyrosine kinases is a low-abundance protein.
A scarce, soluble, conserved protein was identified as the nonphosphorylated precursor of two related 42-kilodalton phosphoproteins that contain phosphotyrosine in mitogen-stimulated but not control fibroblasts.
