PDCD6IP (Programmed Cell Death 6 Interacting Protein): PDCD6IP is a protein that indicates the balance and regulation of essential cellular processes. Also known as ALIX, it participates in endocytosis, membrane repair, and cell death pathways. PDCD6IP plays a vital role in multivesicular body formation and the budding of enveloped viruses like HIV. Malfunctions in PDCD6IP are linked to neurodegenerative diseases and cancer, highlighting its significance in autophagy, apoptosis, and overall cellular homeostasis.
