VPS37B (Vacuolar Protein Sorting 37 Homolog B) is a core component of the ESCRT-I (Endosomal Sorting Complex Required for Transport-I) complex, critical for endosomal trafficking and multivesicular body (MVB) formation[@structure2009]. The ESCRT machinery is essential for sorting ubiquitinated cargo into intralumenal vesicles of MVBs, which subsequently fuse with lysosomes for degradation. VPS37B dysfunction has been implicated in neurodegenerative diseases including Parkinson's disease and Alzheimer's disease through impaired protein clearance and autophagy[@escrt2015].

The VPS37B gene is located on chromosome 14q23.3 and encodes a 184-amino acid protein. VPS37B forms part of the heterotetrameric ESCRT-I complex (composed of VPS37A/B, VPS28, VPS37, and MVB12) that functions downstream of ESCRT-0 and ESCRT-I to drive membrane invagination and cargo sorting into MVBs.
