ATP2A1

简介
ATP2A1 is critical for striated muscle function, acting as the primary Ca(2+) ATPase to efficiently reuptake cytosolic Ca(2+) into the sarcoplasmic reticulum. Through ATP hydrolysis, ATP2A1 transfers calcium from the cytoplasm to the sarcoplasmic reticulum lumen, which is critical for precise control of calcium levels, regulation of isolation, and control of muscle excitation and contraction dynamics. ATP2A1 Protein, Human (Cell-Free, His) is the recombinant human-derived ATP2A1 protein, expressed by E. coli Cell-free, with N-10*His labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
-
Shipping
In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.

Protein Description
ATP2A1, also known as sarcoplasmic reticulum Ca²⁺-ATPase 1 (SERCA1), plays a crucial role in calcium homeostasis within muscle cells, particularly in skeletal muscle. It is responsible for the reuptake of calcium ions from the cytosol back into the sarcoplasmic reticulum, thereby facilitating muscle relaxation after contraction. Dysregulation of ATP2A1 expression and activity has been linked to various muscular diseases, including myopathies and muscle fatigue disorders. Given its significance, researchers have sought to explore the biochemical properties and functional mechanisms of ATP2A1 through recombinant protein technologies. Expression of recombinant ATP2A1 enables detailed studies on its structure-function relationship, ion transport mechanisms, and interaction with regulatory proteins. Moreover, understanding the role of ATP2A1 in muscle physiology and pathology can inform potential therapeutic strategies for muscle-related conditions. Thus, the study of ATP2A1 recombinant protein has both fundamental and clinical implications, contributing to the broader understanding of calcium signaling in muscle health and disease.
