Nuclear calcium levels affect gene expression, but little is known about how they are regulated. The authors show that large-conductance calcium-activated potassium (BK) channels are present on the nuclear envelope in rodent hippocampal neurons. Blockade of nuclear BK channels revealed that they regulate nucleoplasmic Ca2+, gene expression and dendritic arborization.
