VPS37A (Vacuolar Protein Sorting 37 Homolog A) is a conserved eukaryotic protein that serves as a critical subunit of the Endosomal Sorting Complex Required for Transport-I (ESCRT-I), a multi-protein machinery essential for membrane remodeling and cargo sorting. It plays a pivotal role in diverse cellular processes, including multivesicular body (MVB) formation, cytokinesis, viral budding, and autophagy. Structurally, VPS37A interacts with other ESCRT-I components (e.g., TSG101) via its conserved VPS28-binding domain and anchors the complex to endosomal membranes by associating with ubiquitinated cargo through its ubiquitin-binding UBW motif.
Recombinant human VPS37A protein, typically produced in bacterial or eukaryotic expression systems with tags (e.g., His-tag) for purification, enables in vitro studies of ESCRT-I assembly, membrane trafficking mechanisms, and disease-related dysfunctions. Altered VPS37A expression or mutations have been linked to cancer progression, neurodegenerative disorders (e.g., Parkinson’s), and impaired viral budding (e.g., HIV-1). Its role in maintaining genomic stability during cell division further underscores its therapeutic relevance. Structural studies of recombinant VPS37A also aid in mapping interaction interfaces and developing inhibitors targeting ESCRT-dependent pathways. Research continues to explore its diagnostic and therapeutic potential in membrane-associated pathologies.
