Commun. 12:5494-5494(2021). CC -!- FUNCTION: Brassicaceae-specific phytocytokine (plant endogenous peptide CC released into the apoplast) perceived by MIK2 in a BAK1/SERK3 and SERK4 CC coreceptors-dependent manner, that modulates various physiological and CC antimicrobial processes including growth prevention and reactive oxygen CC species (ROS) response regulation (By similarity). Prevents general CC growth and development (PubMed:31001913). CC {ECO:0000250|UniProtKB:B3H7I1, ECO:0000269|PubMed:31001913}. CC -!- SUBUNIT: Interacts with MIK2 (via extracellular leucine-rich repeat CC domain); this interaction triggers the formation of complex between CC MIK2 and the BAK1/SERK3 and SERK4 coreceptors, and subsequent BAK1 CC activation by phosphorylation. {ECO:0000250|UniProtKB:B3H7I1}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:31001913}. CC Secreted, extracellular space, apoplast {ECO:0000269|PubMed:31001913}. CC Note=The precursor of STMP4 accumulates at the plasma membrane and is CC proteolytically cleaved to release the STMP4 in the apoplasm. CC {ECO:0000269|PubMed:31001913}. CC -!- TISSUE SPECIFICITY: Mostly expressed in leaves and stems, and, to a CC lower extent, in roots, siliques, seeds and flowers. CC {ECO:0000269|PubMed:31001913}. CC -!- INDUCTION: Induced by drought, salt stress, jasmonate (MeJA), ethylene CC (ET) and salicylic acid (SA), mainly in shoots. CC {ECO:0000269|PubMed:31001913}. CC -!- DISRUPTION PHENOTYPE: Slightly increased growth and fresh weight. CC {ECO:0000269|PubMed:31001913}. CC -!- SIMILARITY: Belongs to the serine rich endogenous peptide (SCOOP) CC phytocytokine family. {ECO:0000305}.
