PD-ECGF/Thymidine Phosphorylase: Proteins and Enzymes

PD-ECGF was originally isolated as a platelet-derived endothelial cell mitogen (based on its ability to stimulate 3H-thymidine incorporation) and its cDNA was cloned from a human placental cDNA library. In solution, PD-ECGF exists as a non-disulfide linked homodimer. The sequence of human PD-ECGF is identical to that of human thymidine phosphorylase (dThdPase).
