Function

MIK2_ARATH Acts as a receptor of SCOOP peptides from Brassicaceae plants regulating multiple processing including plant growth, development and stress responses (PubMed:33514716, PubMed:34535661). Perception of SCOOP peptides induces the association of MIK2 with the coreceptors BAK1/SERK3 and SERK4 and relays the signaling through the activation of receptor-like cytosolic kinases (RLCKs) BIK1 and PBL1 (PubMed:33514716, PubMed:34535661). Also able to detect SCOOP-like proteins (SCOOPL) present in fungal Fusarium spp. and bacterial Comamonadaceae to elicit various immune responses, including growth inhibition, ROS production, calcium Ca(2+) influx, MAPK activation and MYB51 promoter activation in roots, thus being required for resistance to several root pathogens (PubMed:33514716, PubMed:34535661). Involved in the pollen tube perception of the female signal (PubMed:26863186). Required to trigger defense responses toward generalist herbivores such as Spodoptera littoralis, probably via the activation of jasmonate and indole glucosinolate biosynthesis (PubMed:35401621).^[1] ^[2] ^[3] ^[4]
