A cyclic promoter of Cyclin E from human genome

This part is a cyclic promoter of protein Cyclin E from human genome. It can lead to transcription of the downstream DNA sequence once in every G1 phase[1,2]

You may use this part to:

1) Express something in mammal cell lines particularly in G1 phases or once in every cell cycle by stable transfecting it into cell line;

2) Use it as a human promoter by transient transfecting it into cells.

Source:

The sequence was retrieved from Addgene. We got it from human genome through PCR using the following primers:

pCCNE-F: CGTGTTTACATTCCACCCGCGCCA

pCCNE-R: TGATGGGGCTGCTCCGGCCT

Promoter function confirmation

G1 promoter function confirmation by transient transfection using 293T cells. Photos taken 48 hours after transient transfection, 10x. pCDK4, pKi67 and pCCNE are our G1 promoters. pmPGK is the constitutive promoter of mouse PGK, it is a medium promoter, here used as a control.
