Software for designing cell pathways - (Jan/11/2013 )

Hi, I need your advice on finding a software in order to design a cellular signalling cascade, from extracellular ligand to nuclear events. Is anyone here familiar with such a program? I know that i t can be done manually in powerpoint but I need something more specific. Thank you in advance

I think people are doing for there own signalling pathway by Illustrator. But that takes a liitle bit time. Maybe this website will help you:
