PIP2-1 Antibody

1. Phosphorylation of AtPIP2;1 Ser121 by BAK1 and/or OST1 is triggered in response to flg22 to activate its water and H2O2 transport activities. PMID: 28784763
2. PIP2;1 activity is regulated by by Ca(2+) and pH. PMID: 27620834
3. study reveals that C-terminal phosphorylation of a water channel subunit, PIP2;1, is upregulated by an EIN3EIL1-independent ethylene signaling pathway and its water transport activity is enhanced by phosphorylation at the C-terminal S280 and S283 sites PMID: 26476206
4. This work supports a model whereby abscissic acid-triggered stomatal closure requires an increase in guard cell permeability to water and possibly hydrogen peroxide, through OST1-dependent phosphorylation of PIP2;1 at Ser-121. PMID: 26163575
5. PIP2;1 molecules are heterogeneously distributed on the plasma membrane and that clathrin and membrane raft pathways cooperate to mediate the subcellular trafficking of PIP2;1. PMID: 22010034
6. Co-expression of AtPIP2;1-GFP and AtPIP1;4-mCherry constructs suggested that ER-retained AtPIP2;1-GFP may interact with other PIPs to hamper their trafficking to the PM, thereby contributing to inhibition of root cell hydraulic conductivity PMID: 21182578
7. analysis of the subcellular trafficking of AtPIP2 PMID: 18234664
8. Structure-function analysis of plant aquaporin AtPIP2. PMID: 18637793
