KLF5（Kruppel like factor 5），癌症关联基因，基因ID：688，该基因编码锌指蛋白Kruppel样因子亚家族的一个成员编码蛋白是一种转录激活剂，它直接与目标基因启动子中的特定识别基序结合该蛋白作用于多种不同的信号传导途径的下游，并通过翻译后修饰进行调节。它可能参与促进和抑制细胞增殖这种基因的表达可能在多种不同的癌症和心血管疾病中发生改变选择性剪接导致多个转录变体[ RefSeq，2013月11日]This gene encodes a member of the Kruppel-like factor subfamily of zinc finger proteins. The encoded protein is a transcriptional activator that binds directly to a specific recognition motif in the promoters of target genes. This protein acts downstream of multiple different signaling pathways and is regulated by post-translational modification. It may participate in both promoting and suppressing cell proliferation. Expression of this gene may be changed in a variety of different cancers and in cardiovascular disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Nov 2013]。
