Chemical activators of copine 5 employ a variety of cellular mechanisms to achieve its functional activation. Forskolin is known to directly stimulate adenylate cyclase, which increases cyclic AMP (cAMP) levels within cells. This elevation in cAMP leads to the activation of Protein Kinase A (PKA), which in turn can phosphorylate copine 5, leading to its activation. Similarly, the cAMP analog 8-Bromo-cAMP can permeate cell membranes and activate PKA, thereby promoting the phosphorylation and activation of copine 5. Another activator, Phorbol 12-myristate 13-acetate (PMA), is effective in activating Protein Kinase C (PKC), a family of enzymes that phosphorylate a wide range of target proteins. Activation of PKC by PMA can also result in the phosphorylation and functional activation of copine 5.
In addition to these mechanisms, the elevation of intracellular calcium is another pathway through which copine 5 can be activated. Ionomycin and A23187 are calcium ionophores that increase intracellular calcium concentration, which can activate calcium-dependent protein kinases capable of phosphorylating copine 5. Thapsigargin contributes to the rise in cytosolic calcium levels by inhibiting the sarcoplasmic/endoplasmic reticulum Ca2+ ATPase (SERCA), which can similarly lead to the activation of copine 5 through calcium-sensitive pathways. Sphingosine-1-phosphate (S1P) activates its G-protein-coupled receptors, which can initiate signaling cascades involving downstream kinases that phosphorylate copine 5. Additionally, Okadaic Acid and Calyculin A maintain proteins in their phosphorylated state by inhibiting protein phosphatases such as PP1 and PP2A, which could result in sustained activation of copine 5 if it is subject to regulation by phosphorylation. Lastly, Epidermal Growth Factor (EGF) stimulates its receptor tyrosine kinase, setting off a cascade that may include the phosphorylation and activation of copine 5. Bisindolylmaleimide I (BIM I), through its inhibition of PKC, can induce alternative pathways that might lead to copine 5 activation if there is interplay between PKC-regulated signaling and pathways that modulate copine 5 activity.

PMA activates Protein Kinase C (PKC), which is known to phosphorylate a wide range of target proteins. Activation of PKC can lead to phosphorylation of copine 5, hence functionally activating it as part of the PKC signaling pathway. | ||||||
Ionomycin | 56092-82-1 | sc-3592 sc-3592A | 1 mg 5 mg | $76.00 $265.00 | 80 | |
Ionomycin acts as a calcium ionophore, increasing intracellular calcium concentration. Elevated calcium levels can activate calcium-dependent protein kinases, which in turn could phosphorylate and functionally activate copine 5. | ||||||

Okadaic Acid is a potent inhibitor of protein phosphatases PP1 and PP2A, maintaining proteins in a phosphorylated state. By inhibiting the dephosphorylation, it could maintain copine 5 in an activated state if copine 5 is regulated by phosphorylation. | ||||||
Anisomycin | 22862-76-6 | sc-3524 sc-3524A | 5 mg 50 mg | $97.00 $254.00 | 36 | |
Anisomycin activates stress-activated protein kinases, such as JNK. The JNK pathway, when activated, can lead to the phosphorylation and activation of specific proteins, potentially including copine 5 if it is a substrate of JNK or related kinases. | ||||||
