Histamine is a chemical substance released in inflammatory and allergic response. The histamine H1 receptor is a G protein-coupled receptor that activates phospholipase C in response to the binding of histamine. Arrange the data below showing the process of histamine signal transduction from the H1 receptor. Calcium ions flow through ligand-gated ion channel. Phosphorylation cascade leads to the activation of a cellular response. Calcioum ions activate a protein, leading to a cellular response. Enzyme cleaves PIP2, forming DAG and IP3. Calcium iom concentration increases in the cytosol. IP3 binds to a ligand-gated ion channel in thw ER membrane.

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.
