10x[TALA] operator_minimal promoter_fLuciferase

• TALA and TALB labels represents TAL effectors 1257 and 1297 from zebrafish experiments (Sander et al., 2011)
• DNA binding sites for individual TAL effectors are indicated with square brackets [ ].

Introduction

Transcription activation like (TAL) effectors are DNA binding proteins with a high specifity, built from tandem repeats, with near identical seqences, differing only in two amino acids in each repeat called “repeat variable diresidue” (RVD), which determine the specifity for a single nucleotide.(Scholze and Boch, 2011)

We designed our construct with 10 binding sites for TALA, upstream of a minimal promoter (like here). Downstream of the promoter we cloned fLuciferase (firefly luciferase) to function as a reporter.

Characterisation

10x[TALA] operator_minimal promoter was characterised with mCitrine reporter.
