**Background of ATP2A3 Antibody**

The ATP2A3 gene encodes SERCA3 (sarco/endoplasmic reticulum Ca²⁺-ATPase isoform 3), a calcium-transporting ATPase critical for maintaining intracellular calcium homeostasis by pumping cytosolic Ca²⁺ into the endoplasmic reticulum. SERCA3 is expressed in non-muscle tissues, including blood cells, epithelial cells, and neurons, and plays roles in processes like secretion, apoptosis, and signal transduction.

Antibodies targeting ATP2A3/SERCA3 are essential tools for studying its expression, localization, and function. They are widely used in techniques such as Western blotting, immunohistochemistry, and immunofluorescence to investigate SERCA3 dysregulation in diseases. For example, reduced SERCA3 levels are linked to diabetes, certain cancers, and platelet disorders. These antibodies help identify tissue-specific expression patterns and assess SERCA3 as a potential biomarker or therapeutic target.

However, challenges exist in antibody specificity due to high homology among SERCA isoforms (SERCA1-3). Validating antibodies with knockout controls or isoform-specific assays is crucial. Recent studies also explore ATP2A3 antibodies in understanding calcium signaling anomalies in neurodegenerative diseases. Overall, ATP2A3 antibodies remain vital for dissecting calcium-dependent cellular mechanisms and their pathological implications.
