Human TLE1 Antibody Summary

Species Reactivity
Detects human TLE1 in direct ELISAs and Western blots. In direct ELISAs, approximately 10% cross-reactivity with recombinant human (rh) TLE3 and rhTLE4 is observed and less than 5% cross-reactivity with rhTLE2 is observed.
Polyclonal Sheep IgG
Antigen Affinity-purified
E. coli-derived recombinant human TLE1
Accession # Q04724
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Data Example

Western Blot Detection of Human TLE1 by Western Blot. View Larger

Detection of Human TLE1 by Western Blot. 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

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.
