Caveolin-2 is one of the major protein components of cholesterol- and glycosphingolipid-rich flask-shaped invaginations of plasma membrane caveolae. A new body of evidence suggests that caveolin-2 plays an important, and often more direct, role than caveolin-1 in regulating signaling and function in a cell- and tissue type-specific manner. The purpose of this paper is to primarily focus on discussing how these recent discoveries may help better understand the specific contribution of caveolin-2 to lipid raft- and caveolae-regulated cell/tissue-specific signaling and functions.
小窝蛋白-2是质膜小窝中富含胆固醇和糖鞘脂的烧瓶状内陷的主要蛋白质成分之一。新的证据表明,小窝蛋白-2在以细胞和组织类型特异性方式调节信号传导和功能方面发挥着比小窝蛋白-1更重要且通常更直接的作用。本文的目的主要是集中讨论这些最新发现如何有助于更好地理解小窝蛋白-2对脂筏和小窝调节的细胞/组织特异性信号传导及功能的具体贡献。
