Disruption of somitogenesis by a novel dominant allele of Lfng suggests important roles for protein processing and secretion.

Abstract excerpt

Vertebrate somitogenesis is regulated by a segmentation clock. Clock-linked genes exhibit cyclic expression, with a periodicity matching the rate of somite production. In mice, lunatic fringe (Lfng) expression oscillates, and LFNG protein contributes to periodic repression of Notch signaling. We hypothesized that rapid LFNG turnover could be regulated by protein processing and secretion. Here, we describe a novel...
