一般描述
谷蛋白由醇溶蛋白和谷蛋白两个醇溶蛋白家族组成。醇溶蛋白是一种疏水性很强的糖蛋白，溶解性极差。醇溶蛋白可进一步细分为 α-醇溶蛋白类，γ-醇溶蛋白和 ω-醇溶蛋白（基于其在低 pH 下电泳时的迁移率顺序。
应用
小麦来源麦醇溶蛋白用于：
- 胃蛋白酶-胰蛋白酶消化，研究体外麦醇溶蛋白挑战对无麸质饮食（GFD）乳糜泻（CD）患者活检组织的影响
- 制备麦醇溶蛋白，用于抗麦醇溶蛋白抗体测定
- 作为标准品，通过流式细胞仪，定量皮克级的麦醇溶蛋白
生化/生理作用
麦醇溶蛋白包含富含谷氨酰胺和脯氨酸的单体蛋白质家族，其占小麦籽粒总蛋白质含量的 40-50%。 醇溶性麦醇溶蛋白与不溶于醇的谷蛋白聚集形成谷蛋白，这是小麦面团的结构和性质的原因。 麦醇溶蛋白还参与乳糜泻的发病机制，乳糜泻是一种自身免疫性疾病，其中人白细胞抗原 DQ2 和 DQ8 将胶质肽递呈至 T 细胞亚群，诱导促炎细胞因子的释放，进而诱导肠黏膜基质的降解和细胞死亡。B 细胞也被刺激产生谷蛋白特异性和转谷氨酰胺酶 2 (TG2) 特异性抗体，后者可能是由麦醇溶蛋白肽与 TG2 共价结合的呈递所致。
