CC -!- FUNCTION: May modulate the level of one or more small signaling
CC molecules that have a role in regulating meristem function. May play a
CC role in balancing and restricting the meristem-promoting activity of
CC auxin signaling (PubMed:17553903). Involved in ethylene and giberellin
CC (GA) signaling pathways or in a parallel pathway controlling cell and
CC hypocotyl elongation and cellular organization (PubMed:17006669).
CC Involved in abscisic acid (ABA) signaling pathway. Plays a negative
CC role in ABA-mediated seed germination and seedling development
CC (PubMed:23603279). Acts in association with LAMP1 to suppress ectopic
CC stem cell niche formation in the shoot apical meristem (SAM)
CC independently of cytokinin signaling pathway (PubMed:25673776).
CC Modulates responses to ABA, oxidative stress and abotic stress
CC (PubMed:23621575). Acts as negative regulator of the ABA signaling
CC pathway to modulate freezing and drought stress responses. Mediates
CC carbon and amino acid metabolism (PubMed:23621575, PubMed:23603279).
CC May be involved in the acquisition and/or maintenance of seed dormancy
CC (PubMed:21637772). Involved in the regulation of response to heat shock
CC and plant defense (PubMed:27743891). {ECO:0000269|PubMed:17006669,

CC typically from Ac-Asp-Glu or folylpoly-gamma-glutamates.;
CC EC=3.4.17.21; Evidence={ECO:0000305};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;

CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000250|UniProtKB:Q04609};
CC -!- INTERACTION:
CC Q9M1S8; O04379: AGO1; NbExp=2; IntAct=EBI-6912802, EBI-6912745;
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000305|PubMed:25673776}; Single-pass type II membrane protein
CC {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed in all plant parts. Highest levels in the
CC bolt stem, inflorescence, root and silique. Low level in leaves.
CC {ECO:0000269|PubMed:11549767}.
CC -!- INDUCTION: Down-regulated by abscisic acid (ABA).
CC {ECO:0000269|PubMed:23603279, ECO:0000269|PubMed:23621575}.
CC -!- SIMILARITY: Belongs to the peptidase M28 family. M28B subfamily.
CC {ECO:0000305}.
