Application

Application Comment Organism
additional information MAPKK is involved in IPO expression pathway, but the regulatory role of MAPKK in ethylene transduction pathway is in the downstream of Ca2+ accumulation in cytosol. Position of MAPKK in the signal transduction of ethylene is downstream of the dephosphorylated protein(s). The signal induced by ethylene is transferred to dephosphorylated protein(s) first, and then passes to MAPKK to cause the activation of IPO Ipomoea batatas

Inhibitors

Inhibitors Comment Organism Structure
PD98059 MAPKK inhibitor, inhibits IPO expression stimulated by staurosporine Ipomoea batatas

Metals/Ions

Metals/Ions Comment Organism Structure
Ca2+ elevation of cytosolic Ca2+ by ethylene may stimulate protein phosphatase and MAPKK, which finally activates IPO expression Ipomoea batatas
