Preparation and Storage

Background: TLE2

TLE2 (Transducin-Like Enhancer of Split 2; also ESG2 and Grg-2) is an 83-84 kDa member of the WD repeat Groucho/TLE family of transcriptional repressors. It is ubiquitously expressed and is known to antagonize TCF (Wnt)-mediated signaling. TLE2 binds to other family members as a heterooligomer or to itself as a homooligomer. While it possesses no intrinsic DNA-binding activity, it does modulate the activity of multiple factors such as FoxG1, Arx and histone H3. Human TLE2 is 743 amino acids (aa) in length. It contains a Gln-rich region that mediates oligomerization (aa 1-133), a CCN domain that contains an NLS (aa 195-256), and six WD repeats that mediate protein-protein interaction (aa 455-742). There are at least five potential phosphorylation sites that, if used, may account for SDS-PAGE MWs exceeding 95 kDa. Potential isoform variants exist. One possesses a 21 aa substitution for aa 1-9, while a second shows the same substitution coupled to an additional 10 aa substitution for aa 683-743. A third isoform possesses an alternative start site at Met56 coupled to a deletion of aa 124-190. Over aa 11-193, human TLE2 shares 91% aa identity with mouse TLE2.
