Biochemistry
Linked via "protein kinases"
Signal Transduction Cascades
Cells respond to external stimuli (hormones, growth factors) through elaborate networks of signal transduction pathways. These pathways typically involve receptor binding, activation of secondary messengers (like cyclic AMP or calcium ions), and phosphorylation cascades m… -
Enzymatic Function
Linked via "protein kinases"
Covalent Modification
Many enzymes are regulated by the reversible covalent attachment or removal of chemical groups. Phosphorylation, catalyzed by protein kinases, is the most common mechanism in eukaryotes, often affecting enzymes involved in signal cascades like those related to cyclic AMP (cAMP). Acetylation and [adenylation](/entries/adenylation…
