Reconstitution notes
To use as WB control, resuspend the lyophilizate in 50 µL of LDS* Sample Buffer to have a final concentration of 2 mg/ml. For reducing conditions, we recommend a final concentration of 0.1 M DTT.*Usage of SDS sample buffer is not recommended with these lyophilized lysates.
-
Notes
Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version - found here. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.
Access thousands of knockout cell lysates, generated from commonly used cancer cell lines.

Target

Function
Transcriptional corepressor that binds to a number of transcription factors. Inhibits NF-kappa-B-regulated gene expression. Inhibits the transcriptional activation mediated by FOXA2, and by CTNNB1 and TCF family members in Wnt signaling. The effects of full-length TLE family members may be modulated by association with dominant-negative AES. Unusual function as coactivator for ESRRG. -
Tissue specificity
In all tissues examined, mostly in brain, liver and muscle. -
Sequence similarities
Belongs to the WD repeat Groucho/TLE family.
Contains 6 WD repeats. -
Domain
WD repeat Groucho/TLE family members are characterized by 5 regions, a glutamine-rich Q domain, a glycine/proline-rich GP domain, a central CcN domain, containing a nuclear localization signal, and a serine/proline-rich SP domain. The most highly conserved are the N-terminal Q domain and the C-terminal WD-repeat domain. -
Post-translational
modificationsPhosphorylated, probably by CDK1. The degree of phosphorylation varies throughout the cell cycle, and is highest at the G2/M transition. Becomes hyperphosphorylated in response to cell differentiation and interaction with HES1 or RUNX1.
Ubiquitinated by XIAP/BIRC4. -
Cellular localization
Nucleus. Nuclear and chromatin-associated, depending on isoforms and phosphorylation status. Hyperphosphorylation decreases the affinity for nuclear components. - Information by UniProt

Alternative names
- E(Sp1) homolog
- Enhancer of split groucho 1
- Enhancer of split groucho like protein 1

Western blot - Human TLE1 knockout HEK293T cell lysate (ab257240)
Lane 1: Wild-type HEK293T cell lysate (20 µg)
Lane 2: TLE1 knockout HEK293T cell lysate (20 µg)
Lane 3: HepG2 cell lysate (20 µg)
Lanes 1-3: Merged signal (red and green). Green - ab131648 observed at 83 kDa. Red - loading control, ab181602 observed at 37 kDa.
ab131648 Anti-TLE 1 antibody [OTI1F5] was shown to specifically react with TLE 1 in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab265059 (knockout cell lysate ab257240) was used. Wild-type and TLE 1 knockout samples were subjected to SDS-PAGE. ab131648 and Anti-GAPDH antibody [EPR16891] - Loading Control (ab181602) were incubated overnight at 4°C at 1 in 500 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging.
