pubmed:abstractText |
We report that during cortical development in the mouse embryo, reversion-inducing cysteine-rich protein with Kazal motifs (RECK) critically regulates Notch signaling by antagonizing the ectodomain shedding of Notch ligands, which is mediated by a disintegrin and metalloproteinase domain 10 (ADAM10). In the embryonic brain, RECK is specifically expressed in Nestin-positive neural precursor cells (NPCs). Reck-deficient NPCs undergo precocious differentiation that is associated with downregulated Nestin expression, impaired Notch signaling and defective self-renewal. These phenotypes were substantially rescued either by enhancing Notch signaling or by suppressing endogenous ADAM10 activity. Consequently, we found that RECK regulates the ectodomain shedding of Notch ligands by directly inhibiting the proteolytic activity of ADAM10. This mechanism appeared to be essential for Notch ligands to properly induce Notch signaling in neighboring cells. These findings indicate that RECK is a physiological inhibitor of ADAM10, an upstream regulator of Notch signaling and a critical modulator of brain development.
