Epidermal development is a complex process of regulated cellular proliferation, differentiation, and tightly controlled cell death involving multiple cellular signaling networks. Here, we report a first description linking the AAA+ (ATPases associated with various cellular activities) superfamily protein Ruvbl1 to mammalian epidermal development. Keratinocyte-specific Ruvbl1 knockout mice (Ruvbl1K14:Cre) show a severe phenotype including dramatic structural epidermal defects resulting in the loss of the functional skin barrier and perinatal death. Thus, Ruvbl1 is a newly identified essential player for the development of differentiated epidermis in mice.
表皮发育是一个复杂的过程，涉及受调控的细胞增殖、分化以及由多个细胞信号网络严格控制的细胞死亡。在此，我们首次报道了将AAA+（与各种细胞活动相关的ATP酶）超家族蛋白Ruvbl1与哺乳动物表皮发育联系起来。角质形成细胞特异性Ruvbl1基因敲除小鼠（Ruvbl1K14:Cre）表现出严重的表型，包括明显的表皮结构缺陷，导致功能性皮肤屏障丧失和围产期死亡。因此，Ruvbl1是新发现的小鼠分化表皮发育的关键因子。
