What is the official name of the KLLN gene?
The official name of this gene is “killin, p53-regulated DNA replication inhibitor.”
KLLN is the gene's official symbol. The KLLN gene is also known by other names, listed below.

What is the normal function of the KLLN gene?
The KLLN gene provides instructions for making a protein called killin. The activity of the KLLN gene is controlled by a protein called p53 (which is produced from the TP53 gene). Little is known about the function of killin, although it is thought to trigger cells to self-destruct (undergo apoptosis) when they are damaged or no longer needed. In this way, killin helps to prevent abnormal cells from growing and dividing unchecked to form tumors. Based on this role, killin is thought to be a tumor suppressor.
