Structural Insights into L-Type Voltage-Gated Ca2+ Channel (CaV1.2) Activation by CaBP1 The L-type voltage-gated Ca2+ channel (CaV1.2) controls gene expression, cardiac function, and neuronal excitability. Mutations in CaV1.2 that disrupt channel function are implicated in cardiac arrhyt...

The team went to the #biophysical and #modeling side to understand how the CaBP1 protein regulates L-type channels. Great collab with Jim Ames, Hell Lab & #MnMLab

Arterial Myocyte Pannexin 1 Channel Controls Vascular Reactivity in Diabetic Hyperglycemia - PubMed These results suggest a key role for Panx1 in controlling ATP signaling through the P2Y_11L/AC5/AKAP5/PKA/Ca_V1.2 axis in arterial myocytes. This Panx1-led complex modulates cAMP levels, Ca_V1.2 activity, and vascular reactivity in response to diabetic hyperglycemia. Th …

Microvascular Rarefaction in the Sinoatrial Node: A Potential Mechanism for Pacemaker Dysfunction in Early HFpEF

Manning & Rivera et al. (www.jacc.org/doi/10.1016/...) show that pruning just a few capillaries in the SA node plunges the heart’s pacemaker into metabolic overdraft—slowing the rate and jacking up beat-to-beat variability. The physiological equivalent of running on fumes. @jaccjournals.bsky.social

Signaling by intracellular β2-adrenergic receptors regulates AMPA receptor trafficking and synaptic plasticity Lee et al. show that OCT3 and PMAT transport norepinephrine (NE) into neurons to stimulate β2ARs that are in their interior. The ensuing phosphorylation of GluA1 on S845 by PKA drives AMPARs to the su...
