RBP-Jkappa-dependent notch signaling is dispensable for mouse early embryonic development.
The Notch signaling pathway is an evolutionarily conserved signaling system which has been shown to be essential in cell fate specification and in numerous aspects of embryonic development in all metazoans thus far studied. We recently demonstrated that several components of the Notch signaling pathway, including the four Notch receptors and their five ligands known in mammals, are expressed in...
متن کاملNotch4-induced inhibition of endothelial sprouting requires the ankyrin repeats and involves signaling through RBP-Jkappa.
Notch proteins comprise a family of transmembrane receptors. Ligand activation of Notch releases the intracellular domain of the receptor that translocates to the nucleus and regulates transcription through the DNA-binding protein RBP-Jkappa. Previously, it has been shown that the Notch4 intracellular region (N4IC) can inhibit endothelial sprouting and angiogenesis. Here, N4IC deletion mutants ...
متن کاملEBNA3A association with RBP-Jkappa down-regulates c-myc and Epstein-Barr virus-transformed lymphoblast growth.
Epstein-Barr virus nuclear antigen protein 3A (EBNA3A) is one of four EBNAs (EBNA-2, EBNALP, EBNA3A, and EBNA3C) through the cellular DNA sequence-specific transcription factor RBP-Jkappa/CBF-1/CSL and are essential for conversion of primary B lymphocytes to lymphoblastoid cell lines (LCLs). In the present study, we investigated the effects of EBNA3A on EBNA2 activation of transcription in the ...
متن کاملTranscriptional repression by the Epstein-Barr virus EBNA3A protein tethered to DNA does not require RBP-Jkappa.
The Epstein-Barr virus (EBV) proteins EBNA1, EBNA2, EBNA3A, EBNA3C, LMP1 and EBNA-LP are essential for the in vitro immortalization of primary B lymphocytes by EBV. EBNA2 is a transcriptional activator of viral and cellular genes. Both EBNA3A and EBNA3C have been shown to specifically inhibit EBNA2-activated transcription by direct interaction with RBP-Jkappa, a cellular DNA-binding factor know...
متن کاملRBP-J and ITAM crosstalk
Osteoclasts, multinucleated giant cells derived from the monocyte/macrophage lineage, are the exclusive specialized bone-resorbing cells that are indispensable for skeletal development, bone remodeling and repair and mineral homeostasis. Increased osteoclastogenesis leads to excessive bone resorption in osteoporosis and in inflammatory diseases with bone destruction, such as rheumatoid arthriti...
