Numb regulates Notch1, but not Notch3, during myogenesis
In the vertebrate embryo, skeletal muscle is derived from the myotome of the somites. Notch1-3 demonstrate overlapping and distinct expression patterns in mouse somites. Notch1 and Notch2 have been shown to be inhibitors of skeletal myogenesis. The current data demonstrate that Notch3 also is an effective inhibitor of MyoD induced myogenesis. Numb, an adaptor protein that promotes Notch degrada...
متن کاملTwo Isoforms of Npap60 (Nup50) Differentially Regulate Nuclear Protein Import
Npap60 (Nup50) is a nucleoporin that binds directly to importin alpha. In humans, there are two Npap60 isoforms: the long (Npap60L) and short (Npap60S) forms. In this study, we provide both in vitro and in vivo evidence that Npap60L and Npap60S function differently in nuclear protein import. In vitro binding assays revealed that Npap60S stabilizes the binding of importin alpha to classical NLS-...
متن کاملNotch2 and Notch3 Function Together to Regulate Vascular Smooth Muscle Development
Notch signaling has been implicated in the regulation of smooth muscle differentiation, but the precise role of Notch receptors is ill defined. Although Notch3 receptor expression is high in smooth muscle, Notch3 mutant mice are viable and display only mild defects in vascular patterning and smooth muscle differentiation. Notch2 is also expressed in smooth muscle and Notch2 mutant mice show car...
متن کاملNOTCH3 signaling regulates MUSASHI-1 expression in metastatic colorectal cancer cells.
MUSASHI-1 (MSI-1) is a well-established stem cell marker in both normal and malignant colon cells and it acts by positively regulating the NOTCH pathway through inactivation of NUMB, a NOTCH signaling repressor. To date, the mechanisms of regulation of MSI-1 levels remain largely unknown. Here, we investigated the regulation of MSI-1 by NOTCH signaling in colorectal cancer cell lines and in pri...
