视网膜视锥细胞视蛋白基因的选择性表达对于色觉是必不可少的,但是调节这一过程的机制还知之甚少。脊椎动物视杆细胞和中波长敏感(M)视锥细胞都通过抑制短波长敏感(S)视锥细胞分化程序来分化。我们发现,Pias 3在小鼠视锥细胞中激活M视蛋白的表达,抑制S视蛋白的表达,转录因子Trβ2和Rxrγ介导Pias 3在M视锥细胞中的优先表达。最后,我们观察到Pias 3通过调节视锥富集转录因子Rxrγ Rorα和Trβ1直接调节M-和S-视锥视蛋白表达。这项研究表明,光感受器特异性转录因子的Pias 3依赖性SUMO化是一种共同的机制,控制视杆细胞和视锥细胞的亚型规范,调节两种细胞类型中不同的分子靶点。
Selective expression of retinal cone opsin genes is essential for color vision, but the mechanism mediating this process is poorly understood. Both vertebrate rod and medium wavelength-sensitive (M) cone photoreceptors differentiate by repression of a short wavelength-sensitive (S)-cone differentiation program. We show that Pias3 acts in mouse cone photoreceptors to activate expression of M-opsin and repress expression of S-opsin, with the transcription factors Trβ2 and Rxrγ mediating preferential expression of Pias3 in M-cones. Finally, we observe that Pias3 directly regulates M- and S-cone opsin expression by modulating the cone-enriched transcription factors Rxrγ Rorα, and Trβ1. This study reveals that Pias3-dependent SUMOylation of photoreceptor-specific transcription factors is a common mechanism that controls both rod and cone photoreceptor subtype specification, regulating distinct molecular targets in the two cell types.
