Cedars-Sinai study identifies heart-specific protein that protects against arrhythmia

(Cedars-Sinai Medical Center) Researchers at the Cedars-Sinai Heart Institute have identified a heart-specific form of a protein, BIN1, responsible for sculpting tiny folds in pockets that are present on the surface of heart muscle cells. The study provides the first direct evidence of a previously theoretical 'fuzzy space' or 'slow diffusion zone' that protects against irregular heartbeats by maintaining an ideal concentration of electrochemical molecules.
