PIP2;1 activity is regulated by by Ca(2+) and pH.
Title: Non-selective cation channel activity of aquaporin AtPIP2;1 regulated by Ca

Results identified 2 members of the receptor-like kinase (RLK) family (RKL1 (At1g48480) and Feronia (At3g51550)) differentially modulate PIP1;2 and PIP2;1 activity through distinct molecular mechanisms.
Title: Novel Aquaporin Regulatory Mechanisms Revealed by Interactomics.

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
Title: Quantitative and Functional Phosphoproteomic Analysis Reveals that Ethylene Regulates Water Transport via the C-Terminal Phosphorylation of Aquaporin PIP2;1 in Arabidopsis.

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.
Title: Aquaporins Contribute to ABA-Triggered Stomatal Closure through OST1-Mediated Phosphorylation.

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.
Title: Single-molecule analysis of PIP2;1 dynamics and partitioning reveals multiple modes of Arabidopsis plasma membrane aquaporin regulation.
