We describe here a 70 kDa transcription factor A1F-B, which preferentially binds to an element encompassing a CCAAT motif on the rat aldolase B promoter. Comparison of binding specificities, relative molecular masses, and subunit compositions with those of other known CCAAT-binding factors indicated that A1F-B is a novel member of CCAAT-binding factors.
我们在此描述一种70 kDa的转录因子A1F-B，它优先结合大鼠醛缩酶B启动子上包含CCAAT基序的元件。将其与其他已知CCAAT结合因子的结合特异性、相对分子质量和亚基组成进行比较表明，A1F-B是CCAAT结合因子的一个新成员。
