MSI1（musashi RNA binding protein 1），癌症关联基因，基因ID：4440，这个基因编码一个含有两个保守的串联rna识别基序的蛋白质。其他物种中的类似蛋白作为rna结合蛋白发挥作用，在转录后基因调控中发挥中心作用。该基因的表达与胶质瘤和黑色素瘤的恶性程度和增殖活性有关。该基因的假基因位于染色体11q13上。[由RefSeq提供，2008年7月]This gene encodes a protein containing two conserved tandem RNA recognition motifs. Similar proteins in other species function as RNA-binding proteins and play central roles in posttranscriptional gene regulation. Expression of this gene has been correlated with the grade of the malignancy and proliferative activity in gliomas and melanomas. A pseudogene for this gene is located on chromosome 11q13.
