CRZ1, short for Calcineurin-Responsive Zinc Finger 1, is a transcription factor that regulates calcineurin dependent-genes in Candida albicans.[1]
Mechanism of action edit
The cytoplasmic protein Crz1 is dephosphorylated by the calcineurin and is then targeted to the nucleus.[2] The nuclear protein activates the transcription of genes involved in cell-wall maintenance and ion homeostasis.[1][3]
Structure edit
The protein Crz1 possesses a Zinc-Finger motif that binds to a specific motif called CDRE (Calcineurin-Dependent Response Element) present on the promoter of the targeted genes.[3] It also possesses a nuclear localization signal (NLS) at the N-terminal part[4]
