大约十年前发现的暗蛋白 (~720 kDa) 是横纹肌中表达的巨型蛋白家族的成员,对正常肌肉功能至关重要。我们对暗蛋白的了解大部分源于它在心肌和骨骼肌中的功能。然而,最近的证据表明,暗蛋白(“暗蛋白”)的变体在不同的细胞类型中表达,它们有助于不同的细胞过程。暗蛋白的功能障碍或废除也与多种病理状况的发展有关,包括心脏肥大和癌症。在此,我们对暗蛋白进行了概述,重点介绍了新的发现,这些发现证明了它们在细胞信号传导和疾病进展中迄今为止未被怀疑的重要性。
Discovered about a decade ago, obscurin (~720 kDa) is a member of a family of giant proteins expressed in striated muscle that are essential for normal muscle function. Much of what we understand about obscurin stems from its functions in cardiac and skeletal muscle. However, recent evidence has indicated that variants of obscurin (“obscurins”) are expressed in diverse cell types, where they contribute to distinct cellular processes. Dysfunction or abrogation of obscurins has also been implicated in the development of several pathological conditions, including cardiac hypertrophy and cancer. Herein, we present an overview of obscurins with an emphasis on novel findings that demonstrate their heretofore-unsuspected importance in cell signaling and disease progression.
