1.Short description:

This part consists of a TAL Effector (TALEsp1), a TALEsp1-stabilized promoter (pupsp1) and a fluorescent marker (sfGFP). This part was originally designed by Thomas Hale Segall-Shapiro (Shapiro et al) and iGEM Thessaloniki modified it to exclude 2 PstI recognition sites, thus making it RFC[10] compatible .It can be used to achieve stabilised expression of the sfGFP marker, decoupled from gene/plasmid copy number.

2.Biology and Functionality:

Transcription Activator- Like Effectors (TAL Effectors or TALEs) are DNA binding proteins that are naturally expressed by members of the Xanthomonas genus when infecting plants. They contain a central repeat domain which defines their binding to specific promoter sequences in the plant genome, activating transcription and facilitating the bacterial infection. Because of their modular architecture and their ability to recognise specific promoter sequences, TALEs are widely used in genome editing when precise targeting is required. They can be programmed/designed to tightly bind to target sites operating as transcription factors by either activating or repressing transcription initiation or elongation. and either activate or repress transcription.(1)

• DNA binding proteins
• Modular Architecture
• Precise Binding with negligible off target effects
