这个基因编码一个丝氨酸/苏氨酸p21激活激酶家族成员，称为pak蛋白。这些蛋白是连接rhogtpase与细胞骨架重组和核信号传导的关键效应器，它们是小gtp结合蛋白cdc42和rac的靶点。这个特殊的家族成员调节细胞的运动和形态。另外，已经发现该基因编码不同亚型的剪接转录变体。
This gene encodes a family member of serine/threonine p21-activating kinases, known as PAK proteins. These proteins are critical effectors that link RhoGTPases to cytoskeleton reorganization and nuclear signaling, and they serve as targets for the small GTP binding proteins Cdc42 and Rac. This specific family member regulates cell motility and morphology. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2010]
