**Background of Recombinant Human VPS37B Protein**
VPS37B (Vacuolar Protein Sorting 37 Homolog B) is a subunit of the Endosomal Sorting Complex Required for Transport-I (ESCRT-I), a critical machinery involved in membrane remodeling processes such as multivesicular body (MVB) formation, viral budding, and cytokinesis. As part of the ESCRT pathway, VPS37B contributes to the sorting of ubiquitinated cargo proteins into intraluminal vesicles (ILVs) of endosomes, a process essential for lysosomal degradation, receptor downregulation, and cellular signaling regulation. Structurally, VPS37B contains conserved domains that mediate interactions with other ESCRT-I subunits (e.g., TSG101. VPS28) and link ESCRT-I to upstream or downstream components of the pathway.
Recombinant human VPS37B protein is produced via heterologous expression systems (e.g., *E. coli* or mammalian cells) to enable functional and structural studies. Its recombinant form often includes affinity tags (e.g., His-tag) for purification and detection. Research on VPS37B has implications in understanding ESCRT-mediated membrane dynamics, viral pathogenesis (e.g., HIV-1 budding), and cellular processes like autophagy and apoptosis. Dysregulation of VPS37B is linked to cancers, neurodegenerative diseases, and immune disorders, highlighting its potential as a therapeutic target. Current studies focus on elucidating its precise molecular interactions and roles in disease mechanisms.
