ｉｆ２６８基因编码一转录因子ＺＩＦ２６８．在发育的视皮层中，ｚｉｆ２６８基因的表达模式受发育的调节．在具有正常视觉经验的视皮层中，ｚｉｆ２６８基因有较高水平的表达．视觉废置后，视皮层内该基因的表达水平显著降低．通过视觉刺激可显著增强该基因的表达．有关ｚｉｆ２６８基因表达模式的研究对于阐明该基因在哺乳动物视觉系统中的生理功能起到借鉴的作用 The if268 gene encodes a transcription factor ZIF268. In the developing visual cortex, the expression pattern of the zif268 gene is regulated by development. In the visual cortex with normal visual experience, the zif268 gene has a higher level of expression. Visual disuse, the visual cortex of the gene expression levels were significantly reduced. Visual stimulation can significantly enhance the expression of the gene. Studies of the zif268 gene expression pattern have served to elucidate the physiological role of this gene in the mammalian visual system
