**Background of FLOT1 Recombinant Protein**
Flotillin-1 (FLOT1), a member of the flotillin family, is a highly conserved, ubiquitously expressed protein implicated in membrane-associated cellular processes. It localizes to lipid rafts, specialized membrane microdomains enriched in cholesterol and sphingolipids, and plays a role in membrane trafficking, signal transduction, and scaffold formation. Structurally, FLOT1 contains an N-terminal SPFH (stomatin/prohibitin/flotillin/HflK/C) domain and a C-terminal coiled-coil region, facilitating its oligomerization and interaction with other proteins.
The recombinant FLOT1 protein is engineered through molecular cloning, where the FLOT1 gene is expressed in heterologous systems (e.g., *E. coli*, mammalian cells) to produce purified, functional protein for research. Recombinant FLOT1 retains its ability to form oligomers and interact with lipid membranes, making it a valuable tool for studying its biological roles *in vitro*.
FLOT1 is involved in diverse pathways, including endocytosis, cell adhesion, and receptor tyrosine kinase signaling. It interacts with signaling molecules like EGFR and integrins, modulating cellular responses. Dysregulation of FLOT1 is linked to pathologies such as cancer, where it promotes tumor progression via enhanced metastasis and drug resistance, and neurodegenerative diseases, where it may influence amyloid precursor protein processing.
Research using recombinant FLOT1 has advanced understanding of its structural dynamics, post-translational modifications (e.g., phosphorylation), and partnerships with cytoskeletal components. These studies highlight its potential as a therapeutic target or biomarker. Overall, FLOT1 recombinant protein serves as a critical reagent for dissecting membrane biology and disease mechanisms.
