The present invention relates to the different roles inorganic ion receptors have in cellular and body processes. The present invention features: (1) molecules which can modulate one or more inorganic ion receptor activities, preferably the molecule can mimic or block an effect of an extracellular ion on a cell having an inorganic ion receptor, more preferably the extracellular ion is Ca
2+
and the effect is on a cell having a calcium receptor; (2) inorganic ion receptor proteins and fragments thereof, preferably calcium receptor proteins and fragments thereof; (3) nucleic acids encoding inorganic ion receptor proteins and fragments thereof, preferably calcium receptor proteins and fragments thereof; (4) antibodies and fragments thereof, targeted to inorganic ion receptor proteins, preferably calcium receptor protein; and (5) uses of such molecules, proteins, nucleic acids and antibodies.
本发明涉及无机离子受体在细胞和身体过程中的不同作用。本发明特点包括:(1) 可以调节一个或多个无机离子受体活性的分子,最好是可以模拟或阻断细胞表面离子对具有无机离子受体的细胞的影响,更好的是细胞表面离子是Ca2+,对具有
钙受体的细胞产生影响; (2) 无机离子受体蛋白及其片段,最好是
钙受体蛋白及其片段; (3) 编码无机离子受体蛋白及其片段的核酸,最好是编码
钙受体蛋白及其片段的核酸; (4) 靶向无机离子受体蛋白的
抗体及其片段,最好是靶向
钙受体蛋白的
抗体; 以及(5) 上述分子、蛋白质、核酸和
抗体的用途。
