NCBI Protein Information
Peptidase M28 family protein
NCBI Summary
Encodes glutamate carboxypeptidase. Various alleles show-increased cotyledon number and rate of leaf initiation, show transformation of leaves to cotyledons, altered flowering time and photomorphogenesis and an increased level of cytokinin biosynthesis. Involved in ethylene enhanced hypocotyl elongation in the light. Strong genetic interaction between TGH and AMP1.

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