ECH1 and neoplasm: Outside of the predicted network based on known interaction of proteins, further cell structural proteins were present (tubulin-specific chaperone A, TBCA; heat-shock protein beta-1, HSPB1; stathmin, STMN1), as well as proteins for tumor survival (serine hydroxymethyl transferase, SHMT2), cell proliferation (tumor protein D52, TPD52), or fatty acid metabolism (delta(3,5)-delta(2,4)-dienoyl-CoA isomerase, ECH1).
