Glutamate receptor 3.4

UniProtKB accession:  Q8GXJ4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Glutamate-gated receptor that probably acts as a non-selective cation channel, at least in hypocotyls (Probable). Can be triggered by Asn, Ser, Gly and, to a lower extent, Ala, Cys and Glu (PubMed:18162597, PubMed:22447719). May be involved in light-signal transduction and calcium homeostasis via the regulation of calcium influx into cells (Probable). Plays an important role in the calcium-based fast transmission of environmental stress (PubMed:15864638). Acts as a negative regulator of lateral root initiation and development (PubMed:23590882). May restrict primordia numbers and position along the root axis by a signaling process originating in the phloem (PubMed:23590882). AtGLR3.4-mediated cytosolic calcium influx may be involved in the regulation of seed germination under salt stress by modulating sodium accumulation through the SOS pathway (PubMed:29432559).
