背景信息

UBAP1 (Ubiquitin-associated protein 1) is a multifunctional protein encoded by the UBAP1 gene, primarily recognized for its role in the endosomal sorting complex required for transport (ESCRT) pathway. As a component of the ESCRT-I complex, UBAP1 facilitates the sorting of ubiquitinated membrane proteins into intraluminal vesicles (ILVs) of multivesicular bodies (MVBs), a critical step in lysosomal degradation and extracellular vesicle biogenesis. Structurally, it contains a ubiquitin-binding UBA domain and a C-terminal STAM-binding region, enabling interactions with ubiquitinated cargoes and other ESCRT subunits. Its function in membrane remodeling and protein trafficking is essential for maintaining cellular homeostasis, autophagy, and receptor downregulation.

UBAP1 has gained attention due to its involvement in neurodegenerative diseases and cancer. Mutations or dysregulation of UBAP1 are linked to hereditary spastic paraplegia (HSP) and amyotrophic lateral sclerosis (ALS), likely through impaired protein quality control. In oncology, UBAP1 overexpression correlates with tumor progression in cancers like hepatocellular carcinoma and glioblastoma, where it may promote invasion and drug resistance by modulating ESCRT-dependent pathways. Additionally, UBAP1 interacts with viral proteins, influencing viral budding in infections like HIV-1.

Recombinant UBAP1 proteins are engineered using expression systems (e.g., E. coli, mammalian cells) for functional studies. These proteins enable in vitro analysis of ESCRT assembly, ubiquitin-dependent cargo recognition, and structural characterization. Researchers also utilize UBAP1 variants to dissect disease mechanisms or screen for therapeutic compounds targeting ESCRT dysfunction. As an emerging biomarker and therapeutic target, UBAP1 continues to inspire studies exploring its molecular interactions and pathophysiological roles.
