Integr. Plant Biol. 62:403-420(2020). 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 STMP6 accumulates at the plasma membrane and is CC proteolytically cleaved to release the STMP6 in the apoplasm. CC {ECO:0000269|PubMed:31001913}. CC -!- TISSUE SPECIFICITY: Mostly expressed in leaves, and, to a lower extent, CC in roots, stems, siliques, seeds and flowers. CC {ECO:0000269|PubMed:31001913}. CC -!- INDUCTION: Induced by cold, drought and salt stress, but repressed by CC pathogenic bacteria Pseudomonas syringae pv. tomato (Pst) DC3000, CC jasmonate (MeJA), ethylene (ET) and salicylic acid (SA), mainly in CC shoots. {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}.
