**Background of TLE3 Recombinant Protein**
TLE3 (Transducin-like enhancer of split 3) is a member of the Groucho/Transducin-like enhancer of split (TLE) family, which functions as transcriptional corepressors. These proteins play critical roles in regulating gene expression by interacting with transcription factors and chromatin-modifying complexes, such as histone deacetylases (HDACs). TLE3 is particularly involved in modulating signaling pathways like Wnt and Notch, which are essential for embryonic development, cell differentiation, and tissue homeostasis. Dysregulation of TLE3 has been implicated in diseases, including cancers and developmental disorders.
Recombinant TLE3 protein is engineered *in vitro* using expression systems like *E. coli* or mammalian cell lines, enabling controlled production for research and therapeutic applications. Its recombinant form retains functional domains, such as the Q, SP, and WD40 repeat regions, which mediate protein-protein interactions and transcriptional repression. Researchers utilize TLE3 recombinant protein to study its role in gene silencing, epigenetic regulation, and pathway crosstalk. In cancer biology, TLE3 is explored as a biomarker or therapeutic target due to its association with tumor suppression or progression, depending on context. Additionally, recombinant TLE3 aids in structural studies, drug screening, and understanding mechanisms underlying developmental defects linked to TLE family dysfunction. The protein’s versatility and pivotal regulatory roles make it a valuable tool in both basic and applied biomedical research.
