CC -!- FUNCTION: Cell signaling peptide that may regulate plant stress,
CC growth, and development. Mediates a rapid alkalinization of
CC extracellular space by mediating a transient increase in the
CC cytoplasmic Ca(2+) concentration leading to a calcium-dependent
CC signaling events through a cell surface receptor and a concomitant
CC activation of some intracellular mitogen-activated protein kinases (By
CC similarity). Regulates negatively brassinolide (BL)-mediated signaling
CC pathway (e.g. BL-induced hypocotyl elongation and branching limitation)
CC (PubMed:19473327). {ECO:0000250, ECO:0000269|PubMed:19473327}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: In very young seedlings, confined to the tips of
CC the cotyledons. Later expressed in the cotyledon vasculature and
CC petiole. Present in the tip of emerging leaves. In mature leaves,
CC observed in the vasculature. {ECO:0000269|PubMed:19473327}.
CC -!- INDUCTION: Repressed by brassinolide (BL) treatment.
CC {ECO:0000269|PubMed:19473327}.
CC -!- PTM: Proteolytically cleaved, probably by SBT6.1 (S1P), a subtilisin-
CC like serine protease (subtilase). {ECO:0000269|PubMed:19473327}.
CC -!- SIMILARITY: Belongs to the plant rapid alkalinization factor (RALF)
CC family. {ECO:0000305}.
