The present invention relates to nucleotide sequences of clk-2 genes, particularly human clk-2, and amino acid sequences of their encoded proteins, as well as derivatives and analogs thereof. The present invention also relates to methods and compositions designed for the treatment, management, or prevention of disorders associated with abnormal expression and/or activity of clk-2 nucleic acids and/or proteins. In one embodiment, the invention encompasses a method of treating or preventing a disorder associated with decreased apoptosis (e.g., cancer, autoimmune disorders) or decreased telomere length (e.g., rapid aging or advanced age) by administering to a subject in need thereof an effective amount of an agent that promotes clk-2 activity. In another embodiment, invention encompasses a method of treating or preventing a disorder associated with increased apoptosis (e.g., neurodegenerative disorders) and increased telomere length (e.g., cancer) such as by administering to a subject in need thereof an effective amount of an agent that decreases clk-2 function. Diagnostic methods and methods for screening for therapeutically useful agents are also provided.
本发明涉及clk-2基因(特别是人类clk-2基因)的核苷酸序列和其编码蛋白的氨基酸序列,以及它们的衍生物和类似物。本发明还涉及用于治疗、控制或预防与 clk-2 核酸和/或蛋白质异常表达和/或活性相关的疾病的方法和组合物。在一个实施方案中,本发明包括一种治疗或预防与细胞凋亡减少(如癌症、自身免疫性疾病)或端粒长度减少(如快速衰老或高龄)相关的疾病的方法,其方法是向有需要的受试者施用有效量的促进clk-2活性的制剂。在另一个实施方案中,本发明包括一种治疗或预防与细胞凋亡增加(如神经退行性疾病)和端粒长度增加(如癌症)相关的疾病的方法,例如通过向有需要的受试者施用有效量的降低clk-2功能的制剂。此外,还提供了诊断方法和筛选治疗有用制剂的方法。
