HEY1（hes related family bHLH transcription factor with YRPW motif 1），癌症关联基因，基因ID：23462，该基因编码一种核蛋白，属于碱性螺旋环螺旋（bhlh）型转录抑制因子的分裂相关（hesr）家族的多毛增强因子。Notch和c-Jun信号转导途径诱导该基因的表达小鼠胚胎心血管发育需要两个相似和冗余的基因，它们也参与神经发生和体细胞发生。选择性剪接导致多个转录变体[由RefSeq提供，2008年7月]This gene encodes a nuclear protein belonging to the hairy and enhancer of split-related (HESR) family of basic helix-loop-helix (bHLH)-type transcriptional repressors. Expression of this gene is induced by the Notch and c-Jun signal transduction pathways. Two similar and redundant genes in mouse are required for embryonic cardiovascular development， and are also implicated in neurogenesis and somitogenesis. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Jul 2008]。
