心房利鈉肽
心房利鈉肽(英語: or atrial natriuretic factor (ANF) ),又稱心鈉素、利鈉素、利尿素、血管舒張素、心房排鈉肽。屬於利鈉肽()家族之一員,其另包含腦利鈉肽()和C型利鈉肽()。心房利鈉肽是一種肽荷爾蒙,主要由心房的心肌細胞生產、儲存和分泌,含有28個胺基酸,在第7和第23胺基酸位置由兩個半胱胺酸殘基以雙硫鍵鍵結形成一環狀結構。[1]
心房利鈉肽的受體
心房利鈉肽有三種細胞表面受體,分別是ANPA、ANPB和ANPC。其中ANPA與ANPB受體有鳥苷酸環化酶活性,並且藉由環鳥苷酸調控下游機制。ANPC受體的功能主要是將心房利鈉肽從循環系統中清除。所有的利鈉肽都能夠與ANPC受體結合。心房利鈉肽和腦利鈉肽結合在ANPA上,而C型利鈉肽則是和ANPB結合。[3]
其他利鈉肽因子
除了哺乳動物的利鈉肽(心房利鈉肽、腦利鈉肽, 和C型利尿鈉肽),還有另外兩種利鈉肽已經被分離出來。Tervon (1998) 發現一種鮭魚利鈉肽,和哺乳動物的利鈉肽有相似的結構和特性。[6]曼巴蛇屬利鈉肽則在綠色曼巴蛇的毒液中被發現。[7]
