該基因產物屬于14-3-3蛋白家族，通過與含磷酸絲氨酸的蛋白質結合介導信號轉導。這種高度保守的蛋白質家族在植物和哺乳動物中都有發現，這種蛋白質與小鼠、大鼠和綿羊的同源基因99%相同編碼蛋白與IRS1蛋白相互作用，提示其在調節胰島素敏感性中起作用在5’UTR中有幾個不同但編碼相同蛋白質的轉錄變體已經被鑒定為該基因。
This gene product belongs to the 14-3-3 family of proteins which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals, and this protein is 99% identical to the mouse, rat and sheep orthologs. The encoded protein interacts with IRS1 protein, suggesting a role in regulating insulin sensitivity. Several transcript variants that differ in the 5' UTR but that encode the same protein have been identified for this gene.
