CDK5

该基因编码一种脯氨酸导向的丝氨酸/苏氨酸激酶，是细胞周期蛋白依赖性激酶家族的成员。与这个家族的其他成员不同，这个基因编码的蛋白质并不能直接控制细胞周期的调节。相反，这种蛋白主要在哺乳动物有丝分裂后的中枢神经系统神经元中高水平表达，通过细胞骨架组织、胞内和胞外以及细胞凋亡所需的蛋白质磷酸化，在突触可塑性和神经元迁移等多种过程中发挥作用。在人类中，导致无法检测到蛋白质水平的基因等位变异与致死性常染色体隐性Lissencephary-7相关。选择性剪接导致多个转录变体。[由RefSeq提供，2015年5月]
This gene encodes a proline-directed serine/threonine kinase that is a member of the cyclin-dependent kinase family of proteins. Unlike other members of the family, the protein encoded by this gene does not directly control cell cycle regulation. Instead the protein, which is predominantly expressed at high levels in mammalian postmitotic central nervous system neurons, functions in diverse processes such as synaptic plasticity and neuronal migration through phosphorylation of proteins required for cytoskeletal organization, endocytosis and exocytosis, and apoptosis. In humans, an allelic variant of the gene that results in undetectable levels of the protein has been associated with lethal autosomal recessive lissencephaly-7. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2015]
