TLE1 Antibody

Western blot shows lysates of human muscle tissue and human heart tissue. PVDF Membrane was probed with 2 µg/mL of Human TLE1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5947) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for TLE1 at approximately 100 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background

TLE1 (Transducin-Like Enhancer of Split 1; also ESG1 and GRG1) is a member of the WD repeat Groucho/TLE family of transcriptional repressors. It is widely expressed, and is known to antagonize NFkB and TCF (Wnt)-mediated signaling. TLE1 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 bound transcription factors. Human TLE1 is 770 amino acids (aa) in length. It contains a Gln‑rich region that mediates oligomerization (aa 1-131), a CCN domain that contains an NLS and CDC2 kinase site (aa 200-268), and six WD repeats that mediate protein‑protein interaction (aa 470-767). Phosphorylation on Ser will generate 90-93 kDa and 116 kDa forms in SDS‑Page. Potential splice variants exist. There are alternative start sites at Met57 and Met326, a 10 aa insertion after Gly124, and three distinct eight aa substitutions for aa 193-770, 193-199 and 445-770. Over aa 11-200, human TLE1 shares 98% aa identity with mouse TLE1.
