Immunogen: AT1G66280 Q9C8Y9 Synonyms: BGLU22 Background:
BGLU22 is a Glycosyl hydrolase superfamily protein. In Arabidopsis, three β -glucosidases (AT1G66270-BGLU21, AT1G66280-BGLU22, AT3G09260-BGLU23), which belong to thesubfamily 3 of GH family 1, are known to be root-specificenzymes, and they all share an endoplasmic reticulum (ER)retention signal at their C-terminus. Malboobi and Lefebvre (1997) showed the induction of BGLU21 inresponse to phosphate starvation. -

Immunogen: AT1G66270 Q9C525 Synonyms: BGLU21 Background:
BGLU21 is a beta-glucosidase that has a high level of activity against the naturally occuring secondary metabolite scopolin. Transcript analysis as well as protein extraction and western blotting from various plant organs suggest that BGLU21 is only present in roots and seedlings. -

Immunogen: AT5G23630 Q9LT02 Synonyms: MIA, MALE GAMETOGENESIS IMPAIRED ANTHERS, PDR2, PHOSPHATE DEFICIENCY RESPONSE 2 Background:
PDR2 mediates manganese transport into the endoplasmic reticulum. It plays an important role in pollen and root development through its impact on protein secretion and transport processes. And it functions together with LPR1 and LPR2 in a common pathway that adjusts root meristem activity to phosphate availability. -

Immunogen: AT4G12970 Q9SV72 Synonyms: EPFL9, ATEPFL9, EPIDERMAL PATTERNING FACTOR LIKE-9, STOMAGEN Background:
ATEPFL9 is a cysteine-rich peptide, a secretory factor that is produced in the mesophyll cells and acts on the epidermis to increase stomatal formation. Its mature form is a 45-aa peptide with three intramolecular disulfide bonds. It is proposed that ATEPFL9 increases stomatal number by competing with two negative regulators of stomatal density, EPF1 and EPF2. -

Immunogen: AT4G32650 P92960 Synonyms: KAT3, A. THALIANA LOW-K+-TOLERANT 1, ARABIDOPSIS THALIANA K+ RECTIFYING CHANNEL 1, ATKC1, ATLKT1, KC1, POTASSIUM CHANNEL IN ARABIDOPSIS THALIANA 3 Background:
In Arabidopsis, the Shaker family comprises nine members, which can be segregated into five phylogenetic groups. Group I (KAT1 (AT5G46240) and KAT2 (AT4G18290)), group II (AKT1 (AT2G26650) and AKT5 (AT4G32500)) and group III (AKT2 (AT4G22200)) can produce homotetrameric hyperpolarization-activated K+channels when expressed alone in heterologous expression systems. In the same conditions, group V (GORK (AT5G37500), and SKOR (AT3G02850)) can produce homotetrameric depolarization-activated K+channels. AtKC1, the single member of group IV in Arabidopsis, contributes to the inward K+conductance, probably in association with AKT1 within hetero-meric channels. -

Immunogen: AT4G19640 Q9SN68 Synonyms: ARA7, ARA-7, ARABIDOPSIS RAB GTPASE HOMOLOG F2B, ATARA7, ATRAB-F2B, ATRAB5B, ATRABF2B, RAB GTPASE HOMOLOG F2B, RAB-F2B, RABF2B Background:
ARA7 is a endosomal protein that may be involved in endocytosis. It is involved in the trafficking of proteins from prevacuolar compartments (PVCs) to vacuoles. -

Immunogen: AT4G34460 P49177 Synonyms: AGB1, ATAGB1, ELK4, ERECTA-LIKE 4, GTP BINDING PROTEIN BETA 1 Background:
AGB1 is the heterotrimeric G-protein beta subunit and is involved in organ shape. A significant fraction of the protein is found in the ER. The predicted protein has two DWD motifs. It can bind to DDB1a in Y2H assays and may be involved in the formation of a CUL4-based E3 ubiquitin ligase. It seems to be involved in the calcium-mediated response to extracellular ATP. -

Immunogen: AT3G10800 Q9SG86 Synonyms: BZIP28 Background:
BZIP28 is a putative membrane-tethered transcriptional factor. It has a similar domain structure to the mammalian ATF6 protein involved in the unfolded protein response (UPR), and shares a bZIP domain, transmembrane domain, and a canonical S1P cleavage site. This protein present in root cells appears to translocate from the cytoplasm and ER to the nucleus following TM treatment. -

Immunogen: AT2G43350 O22850 Synonyms: GPX3, ATGPX3, GLUTATHIONE PEROXIDASE 3, GPXL3. Background:
The plant glutathione peroxidase (GPX) family consists of multiple isoenzymes with distinct subcellular locations which exhibit different tissue-specific expression patterns and environmental stress responses. GPX3 (AT2G43350) is one of the subunit. -

Immunogen: AT2G47770 O82245 Synonyms: TSPO, ATTSPO, TSPO (OUTER MEMBRANE TRYPTOPHAN-RICH SENSORY PROTEIN)-RELATED. Background:
AtTSPO is related to the bacterial outer membrane tryptophan-rich sensory protein (TspO) and the mammalian mitochondrial 18 kDa Translocator Protein (18 kDa TSPO), members of the TspO/MBR domain-containing membrane proteins. It is degraded through the autophagy pathway.
