Recombinant human CTNNBL1 (Catenin Beta-like 1) protein is a ubiquitously expressed, evolutionarily conserved protein sharing structural homology with β-catenin. It contains an armadillo (ARM) repeat domain, facilitating protein-protein interactions, but lacks direct involvement in canonical Wnt signaling. CTNNBL1 plays diverse roles in cellular processes, including pre-mRNA splicing, transcriptional regulation, and metabolic pathways. It interacts with components of the spliceosome machinery (e.g., CDC5L) to modulate alternative splicing and with APOBEC3G to regulate its antiviral activity against HIV-1. Structurally, CTNNBL1 forms a complex scaffold for assembling multi-protein complexes. Dysregulation of CTNNBL1 is linked to obesity, metabolic syndromes, and cancer progression, highlighting its physiological and pathological significance. Recombinant CTNNBL1. typically produced in Escherichia coli or mammalian expression systems, enables in vitro studies of its molecular interactions, structural features, and enzymatic functions. Its applications span investigating splicing mechanisms, viral restriction pathways, and metabolic disease mechanisms, making it a critical tool for elucidating CTNNBL1's role in health and disease.
