The transgene construct was designed with the myc peptide tagged mutant (truncated) human DISC1 (disrupted in schizophrenia 1) gene, under the control of tetracycline operator (tetO; also called tetracycline-responsive element (TRE) or tet-operator) sequence and a cytomegalovirus minimal promoter. Line 1302B shows a relatively weak expression of human DISC1. (J:146881)
