Notch signaling orchestrates transition from G1 to S phase of cell cycle by multiple other interactions that target the G1/S checkpoint machinery. This is a highly conserved pathway that is seen across multiple kingdoms of life and the ligands involved in notch signaling are typically membrane-bound proteins. This suggests that:  -This pathway relies on hormone interactions via endocrine pathways -This pathway relies on signal propagation via paracrine molecules -This pathway relies on direct signaling across gap junctions -This pathway relies on cell binding via autocrine signaling

Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.
