ASCL1(Achaete-scute homolog 1)属于碱性螺旋-环-螺旋(bHLH)转录因子家族,在神经发育中起关键作用。它主要调控神经前体细胞的增殖、分化和命运决定,尤其在自主神经系统和中枢神经系统的发育中不可或缺。ASCL1通过结合特定DNA序列(E-box)激活下游靶基因的表达,影响神经内分泌细胞、神经元和神经胶质细胞的生成。突变可能导致神经发育异常,如先天性中枢性低通气综合征(CCHS)或神经内分泌肿瘤。ASCL1过表达会促进神经分化,但也可能诱发小细胞肺癌等恶性肿瘤;表达降低则导致神经前体细胞减少或分化障碍。它与神经母细胞瘤、帕金森病等疾病相关,并参与多能干细胞向神经元的重编程。该基因属于ASCL家族(包括ASCL1-5),家族成员均含bHLH结构域,参与细胞命运决定,尤其在神经和内分泌系统发育中功能保守。ASCL1还与其他bHLH蛋白(如NEUROD1)相互作用,形成调控网络,其表达受NOTCH信号通路抑制,体现发育中的精细平衡。

This gene encodes a member of the basic helix-loop-helix (BHLH) family of transcription factors. The protein activates transcription by binding to the E box (5'-CANNTG-3'). Dimerization with other BHLH proteins is required for efficient DNA binding. This protein plays a role in the neuronal commitment and differentiation and in the generation of olfactory and autonomic neurons. Mutations in this gene may contribute to the congenital central hypoventilation syndrome (CCHS) phenotype in rare cases. [provided by RefSeq, Jul 2008]

该基因编码的碱性螺旋 - 环 - 螺旋(BHLH)家族的转录因子的成员。该蛋白质通过结合到E盒(5‘-CANNTG-3‘)激活转录。与其他bHLH蛋白二聚化所需的有效的DNA结合。此蛋白在神经元的承诺和分化和嗅觉和自主神经元的产生的作用。在这个基因的突变可能有助于在极少数情况下先天性中央低通气综合征(CCHS)表型。 [由RefSeq的,2008年7月提供]
