Interaction was apparently determined by the N - terminal splice region of RPDE - 6 , as the PDE4A splice variant RPDE - 39 , which differs from RPDE - 6 at the extreme N - terminus , failed to associate with v - Src - SH3 ; met26RD1 ( where RD1 is rat ' dunc - like ' PDE ) , which has the N - terminal splice region deleted , failed to associate with v - Src - SH3 , and the association of RPDE - 6 and v - Src - SH3 was blocked by a fusion protein formed from the N - terminal splice region .
 RPDE - 6, PDE4A, RPDE - 39, RPDE - 6, v - Src, SH3, met26RD1, RD1, rat ' dunc - like ' PDE, v - Src, SH3, RPDE - 6, v - Src, SH3
