ARNT基因编码功能及结构描述
该基因编码一个含有一个基本螺旋环螺旋结构域和两个特征性PAS结构域以及一个PAC结构域的蛋白质编码的蛋白质与配体结合的芳香烃受体结合，并有助于该复合物向细胞核移动，在细胞核中促进参与外源代谢的基因的表达该蛋白也是缺氧诱导因子1转录调控的共因子。该位点与12号染色体上的etv6（ets变异体6）基因的染色体易位在白血病中已被描述。选择性剪接导致多个转录变体[由RefSeq提供，2013年10月]
This gene encodes a protein containing a basic helix-loop-helix domain and two characteristic PAS domains along with a PAC domain. The encoded protein binds to ligand-bound aryl hydrocarbon receptor and aids in the movement of this complex to the nucleus, where it promotes the expression of genes involved in xenobiotic metabolism. This protein is also a co-factor for transcriptional regulation by hypoxia-inducible factor 1. Chromosomal translocation of this locus with the ETV6 (ets variant 6) gene on chromosome 12 have been described in leukemias. Alternative splicing results in multiple transcript variants.
