A protein kinase, interacting with two calcineurin B-like proteins, regulates [K.sup.} transporter AKT1 in Arabidopsis
Article Abstract:
The identification and characterization of a regulatory pathway for [K.sup.} uptake in Arabidopsis and also, the identification of two calcinerium B-like (CBL) proteins as the upstream regulators of CIPK23 are reported. The results have shown that an AKT1-mediated and CBL/CIPK-regulated [K.sup.} uptake pathway exists in higher plants that play vital roles in plant [K.sup.} uptake, particularly under [K.sup.}-deficient conditions.

Astrocytes put down the broom and pick up the baton
Article Abstract:
A study is presented to show that D-serine released by astrocytes, a type of glial cell in the brain, promotes NMDA receptor activity at synapses in the hypothalamus. The results confirm that glial cells participate in synaptic signaling and show that they can dictate the tenor of synaptic plasticity.

C2 can do it, too
Article Abstract:
A study conducted reports that the C2 domain of the serine/threonine protein kinase Cdelta is a phosphotyrosine binding domain. Details of the crystal structure of this C2 domain bound to a peptide containing phosphotyrosine are presented.
