Hunter's breakthrough, which set the story in motion, was a product of basic research on a chicken RNA tumor virus: the 1979 discovery of the first tyrosine kinase paved the way for our understanding of how cells perceive their environment and respond appropriately to growth signals.

He has received numerous honors during his distinguished career, including the Nobel Prize in Physiology or Medicine in 1975 for discoveries concerning the interaction between tumor viruses and the genetic material of the cell, and the 1999 National Medal of Science.
