TALB:NLS DNA binding domain
TALB label represents TAL effector 1297 from zebrafish experiments (Sander et al., 2011).
Introduction
TAL effectors (TALEs) are bacterial plant pathogen transcription factors, that bind to DNA by specifically recognizing one base pair with a single tandem repeat in their DNA-binding domain. A tandem TALE repeat contains 33 to 35 amino acids, where the 12th and 13th amino acid, called a “repeat variable diresidue” (RVD), are responsible for specific interactions with the corresponding base pair (Scholze and Boch, 2011).

Single binding sequence for TALB: tCTTCCGTTTCCACATCT
Characterization
TAL effector was obtained via AddGene from Joung's lab and cloned into a biobrick vector. This construct was later used for designing TAL-based activator and repressor by adding VP16 and KRAB domain.
