HCRP1 (Hepatocellular Carcinoma-Related Protein 1), also known as VPS37A, is a member of the vacuolar protein sorting-associated protein 37 family. It was initially identified as a downregulated gene in hepatocellular carcinoma (HCC), suggesting its potential role as a tumor suppressor. The protein is involved in the endosomal sorting complex required for transport (ESCRT) pathway, which regulates membrane remodeling, vesicle trafficking, and protein sorting in cells. Structurally, HCRP1 contains a VPS37 domain critical for interactions with other ESCRT components like TSG101. facilitating cargo recognition and multivesicular body formation.
Studies have linked HCRP1 dysregulation to cancer progression. Its reduced expression in HCC correlates with poor prognosis, enhanced cell proliferation, and metastasis. Mechanistically, HCRP1 loss disrupts epidermal growth factor receptor (EGFR) degradation, leading to sustained oncogenic signaling. Beyond cancer, HCRP1 participates in viral budding (e.g., HIV) and cytokinesis, highlighting its broad cellular functions. Recombinant HCRP1 protein is typically produced in bacterial or mammalian expression systems with tags (e.g., His-tag) for purification. It serves as a vital tool for studying ESCRT-mediated processes, drug screening for cancer therapies, and developing diagnostic biomarkers. Recent research also explores its role in neurodegenerative diseases linked to protein aggregation, expanding its biomedical relevance.
