**Background of LRRFIP1 Recombinant Protein**
LRRFIP1 (Leucine-Rich Repeat Flightless-Interacting Protein 1) is a multifunctional cytosolic protein encoded by the *LRRFIP1* gene in humans. It belongs to the leucine-rich repeat (LRR) protein family, characterized by structural motifs involved in protein-protein interactions. LRRFIP1 contains an N-terminal LRR domain, a central GTP-binding domain, and a C-terminal Flightless-I homologous (FLIH) domain, enabling its interaction with diverse signaling molecules.
Originally identified through its binding to Flightless I (a gelsolin-family actin-remodeling protein), LRRFIP1 is implicated in regulating cellular processes such as cytoskeletal dynamics, inflammation, cancer progression, and antiviral responses. It modulates pathways like Wnt/β-catenin and TGF-β signaling, influencing cell proliferation, differentiation, and apoptosis. In innate immunity, LRRFIP1 interacts with retinoic acid-inducible gene I (RIG-I) or cyclic GMP-AMP synthase (cGAS) to either enhance or suppress interferon production, depending on cellular context. Dysregulation of LRRFIP1 is linked to autoimmune diseases, viral infections, and tumorigenesis.
Recombinant LRRFIP1 protein is produced using prokaryotic (e.g., *E. coli*) or eukaryotic expression systems to study its structure, interactions, and functional mechanisms. Its applications span *in vitro* assays (e.g., pull-down experiments, kinase activity studies) and *in vivo* models to dissect its roles in disease. Recent studies highlight its dual roles in cancer—acting as an oncogene or tumor suppressor—and its potential as a therapeutic target. Additionally, recombinant LRRFIP1 aids in exploring its crosstalk with non-coding RNAs and epigenetic regulators, broadening insights into its regulatory networks.
Overall, LRRFIP1 recombinant protein serves as a critical tool for unraveling its biological significance and translational potential in human health and disease.
