A STK11 gene (also called LKB1) provides instructions for making an enzyme called serine/threonine kinase 11. This enzyme is a tumour suppressor, which means that it helps keep cells from growing and dividing too fast or in an uncontrolled way. This enzyme helps certain types of cells correctly orient themselves within tissues (polarization) and assists in determining the amount of energy a cell uses. This kinase also promotes a type of programmed cell death known as apoptosis. In addition to its role as a tumour suppressor, serine/threonine kinase 11 function appears to be required for normal development before birth.

Distúrbios de armazenamento de glicogênio
Distúrbios de armazenamento de glicogênio are a group of inherited diseases. They result from a problem with one of the proteins (known as enzymes) involved in the conversion of glucose to glycogen, or the breakdown of glycogen back into glucose. They mostly tend to affect your liver and muscles. Most are diagnosed in childhood. Symptoms include weakness,.
