在生物学中,支架蛋白是许多关键信号通路中的重要调控因子。尽管支架蛋白的功能没有被严格定义,但是它们与信号通路中的多个成分互相作用或结合,形成复合体。在这些信号通路中,支架蛋白调控信号转导,并将通路组分(以复合体的形式)定位在细胞的特定区域,诸如细胞膜、细胞质基质、细胞核、高尔基体、内体及线粒体。
RACK1是一种多功能支架蛋白,广泛参与植物生长发育过程的调节。
RACK1 is a scaffold protein with versatile functions, and plays important roles in the regulation of plant growth and development.
支架蛋白iqgap1发现能与许多重要的细胞活动紧密相关,如黏附和迁移。
Scaffold protein IQGAP1 has been found to bear close relationship with many important cell activities, such as adhesion and migration.
所得物保持原来支架的长度和直径,由胶原蛋白和平滑肌细胞组成,其结构类似天然血管。
The result is a tube of the length and diameter of the original scaffold, that is composed of collagen and smooth-muscle cells—a structure similar to a natural blood vessel.
