locus control regions

Locus control regions (LCRs) are official DNA sequences that help regulate gene expression. Think of them as master switches that ensure specific genes are turned on or off at the right times, especially in complex systems like our immune cells or during development. They are located near the genes they control but can influence multiple genes over large DNA distances. By interacting with other regulatory elements, LCRs coordinate gene activity, ensuring proper cell function and development. Their role is crucial in maintaining genetic stability and proper biological responses.
