Description

ATP2A2, also known as SERCA2, serves as a critical calcium-transporting ATPase responsible for maintaining calcium homeostasis within the sarcoplasmic and endoplasmic reticulum. This pump plays an essential role in muscle contraction and relaxation cycles, making it a key target for researchers investigating cardiovascular function, metabolic regulation, and calcium-dependent signaling pathways. Dysregulation of SERCA2 activity has been implicated in heart failure and various disease states, positioning it as an important focus for both basic research and therapeutic development.

This recombinant monoclonal antibody, generated against a synthetic peptide derived from human ATP2A2, offers the consistency and reproducibility that demanding experimental workflows require. As a sequence-defined reagent produced through recombinant technology, clone 20D1 eliminates the lot-to-lot variability often encountered with traditional hybridoma-derived antibodies, ensuring your results remain comparable across extended studies.

Validation across multiple detection platforms demonstrates this antibody's versatility in your research applications. Immunohistochemistry performed on paraffin-embedded human heart tissue using a Leica Bond system shows clear target detection at dilutions of 1:50 to 1:200, with citrate buffer antigen retrieval. Immunofluorescence studies in MCF7 breast cancer cells reveal distinct staining patterns, while flow cytometry analysis of HeLa cells confirms reliable detection of intracellular ATP2A2 with clear separation from isotype control.

The unconjugated format and affinity-purified preparation provide flexibility for pairing with your preferred secondary detection systems. Whether you are exploring calcium signaling mechanisms, characterizing cardiac tissue samples, or investigating SERCA2 expression in cancer cell models, this antibody delivers the performance and reliability needed for publication-quality data.

Target Background

Function

This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol to the sarcoplasmic reticulum lumen. Involved in autophagy in response to starvation. Upon interaction with VMP1 and activation, controls ER-isolation membrane contacts for autophagosome formation. Also modulates ER contacts with lipid droplets, mitochondria and endosomes.; Involved in the regulation of the contraction/relaxation cycle. Acts as a regulator of TNFSF11-mediated Ca(2+) signaling pathways via its interaction with TMEM64 which is critical for the TNFSF11-induced CREB1 activation and mitochondrial ROS generation necessary for proper osteoclast generation. Association between TMEM64 and SERCA2 in the ER leads to cytosolic Ca(2+) spiking for activation of NFATC1 and production of mitochondrial ROS, thereby triggering Ca(2+) signaling cascades that promote osteoclast differentiation and activation.
