Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific name?Potassium channel subfamily K member 4
2. What is the gene locus?Chromosome 1
3. What is KCNK4 and why is it called a tiny gatekeeper?KCNK4 is a protein that builds potassium channels, which are tiny doors that let potassium ions move in and out of cells. These doors help keep the cell’s electrical balance steady.
4. How do KCNK4 channels help brain cells talk to each other?When a brain cell sends a signal, KCNK4 channels let potassium leave the cell. This helps the cell reset and be ready to send another signal.

Neuronal Excitability: The ability of a neuron to generate and propagate electrical signals, essential for communication within the nervous system.
Action Potential: A rapid rise and fall in electrical potential across a neuron's membrane, serving as the fundamental unit of neural signaling.
Genotype-Phenotype Correlation: The relationship between an organism's genetic makeup (genotype) and its observable characteristics (phenotype), particularly in the context of disease.
