ORAI1 tissue expression. ORAI1 protein expression in human tissues isolated from healthy donors incubated with an antibody directed against the C terminus of ORAI1 (for details, see [82]). ORAI1 is detected (arrows) in vascular endothelial cells of blood vessels in thymus (a), spleen (b), and heart (c); cardiac fibroblasts (c); ductal epithelial cells in the exocrine pancreas (d); tubular epithelial cells in the kidney (e); epithelial cells in salivary gland (f), breast (g), and prostate (h); seminiferous tubule cells in the testis (i); and stratified squamous nonkeratinized epithelial cells in the cervix (j).
