The Notch signaling pathway is a highly conserved cell signaling system present in most animals. [1] Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. [2] The notch receptor is a single-pass transmembrane receptor protein.

Notch受体是由Notch基因编码的单跨膜蛋白，在包括人类在内的哺乳动物中发现了 4种Notch受体（Notch 1，2，3，4）。 而Notch配体也是表达于细胞表面的单跨膜蛋白，相邻细胞通过Notch受体和配体的结合，传递Notch信号。 人体有 5种Notch配体，分别是Jagged 1、Jagged 2、Delta 1、Delta 3和Delta 4。 Notch配体与受体结合后触发Notch信号的活化，Notch受体相继发生2次蛋白水解，并进一步转移到细胞核，从而激活靶基因的转录，发挥生物学功能。 Notch信号调节 …

Notch蛋白 （在脊椎动物中为Notch1-Notch4）是一种单通路受体，它们通过与 Delta （或Delta-like）和Jagged/Serrate家族的膜结合配体相互作用而被激活。它们以被切割但否则完整的多肽形式运输到质膜上。

In Drosophila, notch interacts with its cell-bound ligands (delta and serrate), and establishes an intercellular signaling pathway that then plays a key role in development. Homologues of the notch -ligands have also been identified in humans, but precise interactions between these ligands and the human notch homologues remain to be determined.

Notch 受体为单一跨膜蛋白，由功能性胞外 (NECD)、跨膜 (TM) 和胞内 (NICD) 结构域组成。 在接收信号的细胞的内质网 (ER) 和高尔基体 (Golgi) 内，可通过剪切和糖基化对 Notch 受体进行处理，这个过程形成 Ca2+ 稳定的异二聚体，异二聚体由 NECD 组成，NECD 非共价结合嵌入膜中的 TM-NICD（S1 剪切）。 经处理的受体随后通过内体转运到质膜，从而通过 Deltex 调控和 NUMB 抑制的方式与配体结合。 在哺乳动物信号发送细胞中，Delta-like（DLL1、DLL3、DLL4）和 …

2024年5月27日 · Accumulating evidence indicates that the Notch signaling pathway serves as both an oncogenic factor and a tumor suppressor in various cancer types. Dysregulation of this pathway promotes...

The Notch signaling pathway is an evolutionarily conserved, intercellular signaling mechanism essential for proper embryonic development in all metazoan organisms in the Animal kingdom. The Notch proteins (Notch1-Notch4 in vertebrates) are single-pass receptors that are activated by the Delta (or Delta-like) and Jagged/Serrate families of ...
