Restoration of CD2-mediated signaling by a chimeric membrane protein including the cytoplasmic sequence of CD45.


We showed previously that the TCR and CD2 fail to couple efficiently with their signal transduction machinery in J45.01, a CD45-deficient variant of the Jurkat T-cell line. Transfection into J45.01 of a cDNA encoding a chimeric membrane protein containing the cytoplasmic sequence of CD45 and extracellular and transmembrane sequences derived from the A2… (More)
