MAFB（MAF bZIP transcription factor B），癌症关联基因，基因ID：9935，该基因编码的蛋白质是一种碱性亮氨酸拉链（bZIP）转录因子，在血缘特异性造血调控中起重要作用编码的核蛋白抑制ets1介导的髓系细胞中红系特异基因的转录。这个基因不含内含子[由RefSeq提供，2008年7月]The protein encoded by this gene is a basic leucine zipper (bZIP) transcription factor that plays an important role in the regulation of lineage-specific hematopoiesis. The encoded nuclear protein represses ETS1-mediated transcription of erythroid-specific genes in myeloid cells. This gene contains no introns. [provided by RefSeq， Jul 2008]。
