Tyrosine 58-66 ret proto-oncogene Homo sapiens 234-239 8670046-5 1996 Finally, analysis of the enzymic activity of MEN2A and MEN2B tumours confirmed the relative levels of tyrosine phosphorylation observed in Cos cells, indicating that this condition, in vivo, may account for the RET transforming potential.
