Target Information
The KIR2 subunit family includes 2.1, 2.2, 2.3, and 2.4.
Unlike G protein-coupled KIR3 subunits, KIR2.1 requires both phosphorylation by PKA and ATP hydrolysis for functional activity.
KIR2.1 is expressed in the superior and inferior colliculi and the pontine region of the brain, moderating synaptic transmission like other potassium channels.
In the placenta, KIR2.1 is expressed throughout gestation in cytotrophoblast cells.
In the kidney, KIR2.1 colocalizes with KIR5.1 in the proximal tubule.
KIR2.1, 2.2, and 2.3 associate with the membrane-associated guanylate kinase synapse-associated protein 97 (SAP97) in the cerebellum and heart.
Phosphorylation of KIR2.2 by protein kinase A inhibits its association with SAP97.
