M3K18_ARATH | developmental stage | In developing flowers, observed in sepals, anther filaments, ovaries and meristem tissues. Also expressed in root meristem tissues and in areas of lateral root formation. In leaves, detected in guard cells and trichomes. |
M3K18_ARATH | function | Component of the abscisic acid (ABA) signaling pathway that acts as ABA signal transducer in the context of abiotic stresses (PubMed:25680457, PubMed:25720833, PubMed:26443375). Triggers MPK1, MPK2, MPK7 and MPK14 activation in a MKK3-dependent manner and MPK6 activation in a MKK3-independent manner. Mediates the ABA-dependent activation of the MKK3-MPK7 module (PubMed:25720833). Positive regulator of ABA responses leading to the induction of gene expression (e.g. RD29B and RAB18) and involved in various responses including stomatal development, stomatal movement, inhibition of germination and root growth (PubMed:26443375). Promotes leaf senescence (PubMed:25680457). |
M3K18_ARATH | similarity | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. |
M3K18_ARATH | tissue specificity | Expressed in roots, leaves and flowers. |
