ATP2C1 recombinant protein is derived from the ATP2C1 gene, which encodes the human Secretory Pathway Ca²⁺/Mn²⁺ ATPase 1 (SPCA1). This protein belongs to the P-type ATPase family, a group of ion pumps critical for maintaining cellular ion homeostasis. SPCA1 localizes primarily to the Golgi apparatus and secretory pathway compartments, where it actively transports Ca²⁺ and Mn²⁺ ions from the cytosol into these organelles. This activity is essential for regulating intracellular calcium signaling, protein processing, post-translational modifications (e.g., glycosylation), and manganese detoxification.
Mutations in ATP2C1 are linked to Hailey-Hailey disease (HHD), a rare autosomal dominant skin disorder characterized by impaired keratinocyte adhesion and recurrent blistering. The loss of functional SPCA1 disrupts Golgi calcium homeostasis, leading to endoplasmic reticulum stress, abnormal epidermal differentiation, and cell desquamation. Studying recombinant ATP2C1 protein helps elucidate its structural-functional relationships, catalytic mechanisms, and disease-associated variants.
Recombinant ATP2C1 is typically produced in heterologous expression systems (e.g., mammalian, insect, or bacterial cells) to obtain purified, bioactive protein for in vitro studies. Its applications include enzymatic assays to probe Ca²⁺/Mn²⁺ transport kinetics, screening therapeutic compounds for HHD, and structural analysis (e.g., cryo-EM) to resolve pump conformations during ion translocation. Additionally, it serves as a tool to investigate SPCA1's interplay with other calcium-regulating proteins (e.g., SERCA, PMCA) and its role in metal toxicity or neurodegenerative diseases linked to manganese dysregulation. The development of ATP2C1 recombinant protein has significantly advanced research into calcium/manganese biology and epithelial pathophysiology.
