Golgin subfamily A member 1 (GOLGA1)

Golgin subfamily A member 1 (GOLGA1), also known as golgin-97, is a member of the golgin family of proteins localized to the Golgi apparatus, where it plays a fundamental role in vesicular trafficking, specifically in endosome-to-Golgi and intra-Golgi transport. It is important for maintaining Golgi structure, reorganization during mitosis, and is involved in the selective transport of vesicles, including those containing E-cadherin. GOLGA1 has associations with several rare genetic diseases (e.g., Robinow syndrome, spastic paraplegia), and autoantibody responses against this protein are seen in Sjögren's syndrome. It serves more as an intracellular trafficking and structural protein than a canonical therapeutic target like a receptor or enzyme. Although involved in important cellular functions, GOLGA1 is not currently considered a direct therapeutic target (e.g., receptor, enzyme, transporter), nor are there drugs approved or in development that directly interact with it as a mechanism of action. It can be relevant as a potential biomarker for autoimmunity (Sjogren’s syndrome), but is not used in clinical practice as such.
