Cedars-Sinai Study Identifies Heart-Specific Protein That Protects Against Arrhythmia
Cedars-SinaiResearchers 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.
