Signalling Poem 1

A steroid receptor receives
A protease cleaves

A ribosome makes
A proteasome breaks

GPCRs stimulate
Within the cAMP appelate
Although PDE hates
What adenylyl cyclase makes
Together they speak
In a molecular feat
Signals from outside to in

When one shoves the other
The other shoves back
Although the cAMP'd druther
Avoid the PDE hack
But a balance is made
And a signal is sent
Action potentials laid
Or secretory granules rent
And communication is.
