The human reference APOL1 variant G0 (no trypanolytic function in T. brucei rhodesiense) is under the control of the tetracycline responsive promoter element. The pound (#) sign is used when the line number is not specified or lines are pooled. The gene is only expressed in a tetracycline/doxycycline controllable manner when mice carrying this allele also carry a tTA or rtTA allele. (J:251848)
