Abstract:
LIN-12 and GLP-1 are members of the LIN-12/Notch family of receptors that mediate cell-cell interactions during development. The sel-8 gene had been identified previously in a screen for suppressors of a mutation that constitutively activates LIN-12. Here, we report that sel-8 is essential for lin-12- and glp-1-mediated signaling, and that SEL-8 is a glutamine-rich nuclear protein. We postulate that SEL-8 serves as a transcriptional coactivator or as an assembly factor for transcription complexes that contain the LIN-12 or GLP-1 intracellular domains.

Notch Signaling Pathway
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
