MARK2（microtubule affinity regulating kinase 2），癌症关联基因，基因ID：2011，该基因编码丝氨酸/苏氨酸蛋白激酶Par-1家族的一个成员该蛋白是上皮细胞和神经元细胞极性的重要调节因子，通过磷酸化和失活多种微管结合蛋白来调控微管的稳定性。蛋白质定位于细胞膜已发现该基因编码不同亚型的多个转录变体。[由RefSeq提供，2009年7月]This gene encodes a member of the Par-1 family of serine/threonine protein kinases. The protein is an important regulator of cell polarity in epithelial and neuronal cells， and also controls the stability of microtubules through phosphorylation and inactivation of several microtubule-associating proteins. The protein localizes to cell membranes. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq， Jul 2009]。
