BBa_K363001
The consensus calcium dependent response element binding site for the Crz1 activator.
This part is a binding site for the Crz1 transcriptional activator. When placed upstream of a eukaryotic promoter sequence, this sequence results in the calcium dependant transcription of downstream coding sequences given that Crz1 and the upstream signal transducing phosphotase calcineurin are constitutively expressed. The signal cascade occurs when calcineurin binds to cytosolic calcium, activating its phosphotase activity. The active calcineurin dephosphorylates cytoplasmic Crz1, resulting in translocation of Crz1 to the nucleus where it binds to this part and promotes the assembly of general transcription factors at the promoter sequence.
BBa_K363006
A characterized calcium dependent response element binding site for the Crz1 activator
This part is a binding site for the Crz1 transcriptional activator. When placed upstream (~700 bp in the yeast gene FKS2/GSC2) of a eukaryotic promoter sequence, this sequence results in the calcium dependant transcription of downstream coding sequences given that Crz1 and the upstream signal transducing phosphotase calcineurin are constitutively expressed. The signal cascade occurs when calcineurin binds to cytosolic calcium, activating its phosphotase activity. The active calcineurin dephosphorylates cytoplasmic Crz1, resulting in translocation of Crz1 to the nucleus where it binds to this part and promotes the assembly of general transcription factors at the promoter sequence.
Usage and Biology
This part was characterized as part of a larger sequence (see design notes), as it occurs naturally as an activator of the yeast gene FKS2, which is codes for an enzyme involved in spore wall synthesis. We found that applying a voltage of 8V for 40-80 seconds provided maximal induction using our apparatus. This apparatus was, roughly speaking, a cylindrical coaxial electrode that was about .75cm across. We used SC media. For full details, see the 2010 Johns Hopkins Team wiki.

A calcium dependent response element binding site for the Crz1 activator
This part is a binding site for the Crz1 transcriptional activator. When placed upstream of a eukaryotic promoter sequence, this sequence results in the calcium dependant transcription of downstream coding sequences given that Crz1 and the upstream signal transducing phosphotase calcineurin are constitutively expressed. The signal cascade occurs when calcineurin binds to cytosolic calcium, activating its phosphotase activity. The active calcineurin dephosphorylates cytoplasmic Crz1, resulting in translocation of Crz1 to the nucleus where it binds to this part and promotes the assembly of general transcription factors at the promoter sequence.

When placed upstream of a eukaryotic promoter sequence, this sequence results in the calcium dependant transcription of downstream coding sequences given that Crz1 and the upstream signal transducing phosphotase calcineurin are constitutively expressed.
