Ste7 Activators
Ste7 activators, as inferred in this context, encompass a broad range of chemical compounds that influence intracellular signaling pathways, culminating in the activation of MAP kinase kinase proteins such as Ste7. These activators typically act upstream of the kinase cascade, affecting various receptors, enzymes, and secondary messengers which in turn modulate kinase activity. The activation of Ste7 through these chemicals does not always follow a linear path; rather, it involves a complex network of signaling events that offer multiple points of convergence for Ste7 activation.
The chemical activators mentioned such as EGF and PMA, target membrane-bound receptors and enzymes like EGFR and PKC, respectively, which then trigger a cascade of phosphorylation events within the cell. Forskolin, by increasing intracellular cAMP levels, indirectly influences the MAPK pathway through PKA activation. On the other hand, U0126 and SB203580, though primarily inhibitors for certain MAPK pathways, can indirectly promote the activation of alternative pathways that involve Ste7.

PMA | 16561-29-8 | sc-3576 sc-3576A sc-3576B sc-3576C sc-3576D | 1 mg 5 mg 10 mg 25 mg 100 mg | $41.00 $132.00 $214.00 $500.00 $948.00 | 119 | |
PMA is a diester of phorbol and is known to be a potent activator of protein kinase C (PKC). This compound mimics diacylglycerol (DAG), a physiological activator of PKC, thus leading to PKC activation. Since PKC can phosphorylate a wide range of target proteins, the activation of PKC by PMA could potentially lead to the activation of Ste7 by phosphorylation, assuming Ste7 is downstream of a PKC-regulated pathway. | ||||||
Forskolin | 66575-29-9 | sc-3562 sc-3562A sc-3562B sc-3562C sc-3562D | 5 mg 50 mg 1 g 2 g 5 g | $78.00 $153.00 $740.00 $1413.00 $2091.00 | 73 | |
Forskolin is a diterpene that directly stimulates adenylyl cyclase, resulting in increased levels of cyclic AMP (cAMP) within the cell. Elevated cAMP activates protein kinase A (PKA), another kinase that can phosphorylate various substrates in the cell. If Ste7 is modulated by PKA or is part of a cAMP-responsive pathway, forskolin could indirectly enhance Ste7 activity through this signaling cascade. | ||||||
SB 203580 | 152121-47-6 | sc-3533 sc-3533A | 1 mg 5 mg | $90.00 $349.00 | 284 | |
SB203580 is a specific inhibitor of p38 MAP kinase. Inhibition of p38 MAP kinase can lead to changes in upstream or parallel signaling pathways that may affect Ste7 activity if Ste7 is involved in these signaling networks. | ||||||
SP600125 | 129-56-6 | sc-200635 sc-200635A | 10 mg 50 mg | $40.00 $150.00 | 257 | |
SP600125 is an inhibitor of JNK (c-Jun N-terminal kinase), which, by modulating JNK activity, could potentially influence the activity of Ste7 if it is regulated by JNK signaling or if there are compensatory effects within the MAP kinase pathways. | ||||||
LY 294002 | 154447-36-6 | sc-201426 sc-201426A | 5 mg 25 mg | $123.00 $400.00 | 148 | |
LY294002 is a specific inhibitor of phosphatidylinositol 3-kinase (PI3K). PI3K is involved in the AKT signaling pathway, which can cross-talk with other kinase pathways, potentially affecting Ste7 activity indirectly if Ste7 is part of these interconnected pathways. | ||||||
Gö 6983 | 133053-19-7 | sc-203432 sc-203432A sc-203432B | 1 mg 5 mg 10 mg | $105.00 $299.00 $474.00 | 15 | |
Gö 6983 is a pan-PKC inhibitor which, by inhibiting PKC, could potentially modulate Ste7 activity indirectly by altering PKC-mediated signaling pathways that may have an impact on Ste7 function. | ||||||
Rapamycin | 53123-88-9 | sc-3504 sc-3504A sc-3504B | 1 mg 5 mg 25 mg | $63.00 $158.00 $326.00 | 233 | |
Rapamycin inhibits mTOR (mechanistic target of rapamycin), which is a central regulator of cell growth and proliferation. The inhibition of mTOR signaling could affect various downstream signaling pathways, possibly including those regulating Ste7 activity. | ||||||

Okadaic acid is a potent inhibitor of protein phosphatases 1 and 2A, leading to increased phosphorylation levels of various proteins. If Ste7 is normally regulated by dephosphorylation, the inhibition of these phosphatases could result in increased Ste7 activity. | ||||||
Anisomycin | 22862-76-6 | sc-3524 sc-3524A | 5 mg 50 mg | $99.00 $259.00 | 36 | |
Anisomycin is a protein synthesis inhibitor that activates stress-activated protein kinases like JNK and p38. This activation may indirectly influence the Ste7 signaling pathway if Ste7 is modulated by stress-related signaling mechanisms. | ||||||
