19. Physical and functional interactions between protein tyrosine phosphatase alpha, PI 3-kinase, and PKCdelta.

20. In entering mitosis the cell cycle-specific regulation of c-Src by RPTPalpha can occur by dephosphorylation of phospho-Tyr527 that activates c-Src in a reaction catalyzed by the transmembrane receptor-like protein tyrosine phosphatase RPTPalpha.
