**Background of Recombinant Human HGS Protein**
Recombinant human HGS (hepatocyte growth factor-regulated tyrosine kinase substrate), also known as HRS (hepatocyte growth factor-regulated tyrosine kinase substrate), is a multifunctional adaptor protein critical in intracellular trafficking and signaling. HGS is a key component of the ESCRT (Endosomal Sorting Complex Required for Transport) machinery, which mediates the sorting of ubiquitinated membrane proteins into multivesicular bodies (MVBs) for lysosomal degradation. Structurally, HGS contains multiple domains, including a VHS domain, FYVE zinc finger, and ubiquitin-interacting motifs, enabling interactions with signaling molecules, ubiquitinated cargoes, and ESCRT subunits.
Biologically, HGS regulates receptor tyrosine kinase signaling (e.g., EGFR) and vesicular transport, impacting processes like growth factor signaling, autophagy, and viral budding. Dysregulation of HGS is linked to cancer, immune disorders, and neurodegenerative diseases. Recombinant HGS protein, typically produced in *E. coli* or mammalian expression systems, retains functional domains and serves as a tool to study ESCRT-mediated trafficking, ubiquitin-dependent sorting, and disease mechanisms. Its applications span biochemical assays, protein interaction studies, and therapeutic target exploration, offering insights into cellular homeostasis and pathology.
