Cytosolic β-amyloid binding protein 1 (CBARA1), also known as VAC14 or ArPIKfyve, is a key regulatory component of the PIKfyve-FIG4-VAC14 protein complex, which plays a critical role in phosphoinositide metabolism and membrane homeostasis. This multifunctional protein is ubiquitously expressed in mammalian tissues and regulates the synthesis and turnover of phosphatidylinositol 3.5-bisphosphate [PI(3.5)P₂], a signaling lipid essential for endosomal maturation, lysosomal function, and autophagy. Structurally, CBARA1 contains multiple HEAT-repeat domains that mediate protein-protein interactions within the complex.
Genetic studies link CBARA1 dysfunction to neurological disorders and pathological conditions. Knockout models demonstrate embryonic lethality, while mutations are associated with neurodegeneration, peripheral neuropathy, and cataracts. The protein's role in maintaining vesicular trafficking and ion channel regulation has implications in cancer progression and neuronal survival. As a recombinant protein, CBARA1 is typically expressed in mammalian or insect cell systems to preserve post-translational modifications required for its scaffolding function. Current research focuses on its mechanistic involvement in cellular stress responses and potential therapeutic targeting for diseases linked to lysosomal dysfunction.
