a: Protein phosphorylation ~
b: switch on an enzyme
What: "Phosphorylation happens when a phosphate group is added to a protein. Phosphorylation is like a switch that activates proteins, altering their function and changing cell signalling pathways. These signalling pathways are like cellular control panels. Deregulated cell signalling, when the control panel malfunctions, is a common hallmark of disease."

METAMIA is a free database of analogy
and metaphor. Anyone can contribute or search.
The subject matter can be anything.
Science is popular, but poetry is encouraged.
The goal is to integrate our fluid muses with
the stark literalism of a relational database.
Metamia is like a girdle for your muses,
a cognitive girdle.
