cAMP serves as a second messenger in virtually all organisms.
Calcium also serves as a second messenger to control acrosome reaction and sperm motility.
Raucher, D. et al. Phosphatidylinositol 4,5-bisphosphate functions as a second messenger that regulates cytoskeleton-plasma membrane adhesion.
However, free cytosolic Ca2+ may also act as a second messenger and activate many cytosolic proteins involved in apoptotic pathways64.
Calcium as a second messenger is known to play a crucial role in stimulus - response coupling for many plant cellular signaling pathways.
This nucleotide is known as a second messenger, an intracellular signaling molecule produced by enzymes within the cell, which forms part of a signal transduction pathway.
The calcium-signature hypothesis has evolved as a concept to explain specificity in signaling pathways that utilise calcium as a second messenger.
Ca2 + is intracellular divalent cation with the largest concentration variations and involved in many biological phenomena and often acted as a second messenger in signaling pathway.
An autocrine PGE2-mediated migratory activity of these cells appeared to be associated predominantly with EP4 receptor-mediated signaling pathway, which uses cAMP as a second messenger.
Fluorescence imaging of calcium ions (Ca2+) has become an essential technique for investigation of signaling pathways involving Ca2+ as a second messenger.
Calcium ions play key roles as structural components in biomineralization and as a second messenger in signaling pathways.
