The LAMP2 gene provides instructions for making a protein called lysosome-associated membrane glycoprotein 2 (LAMP-2). As its name suggests, this protein is found in the membrane of cellular structures called lysosomes. Lysosomes are compartments in READ MORE

The protein produced from the LARGE1 gene is found in a specialized structure within cells called the Golgi apparatus, where newly produced proteins are modified. The LARGE1 protein is involved in a process called glycosylation. Through this chemical READ MORE

The LARS2 gene provides instructions for making an enzyme called mitochondrial leucyl-tRNA synthetase. This enzyme is important in the production (synthesis) of proteins in cellular structures called mitochondria, the energy-producing centers in cell READ MORE

The LBR gene provides instructions for making a protein called the lamin B receptor. Different regions (domains) of this protein give it two distinct functions. One region of the protein, called the sterol reductase domain, gives the protein sterol r READ MORE

The LCAT gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT). This enzyme plays a role in removing cholesterol from the blood and tissues. Cholesterol is a waxy, fat-like substance that is produced in th READ MORE

The LCT gene provides instructions for making an enzyme called lactase. This enzyme helps to digest lactose, a sugar found in milk and several other dairy products. Lactase is produced by some of the cells that line the walls of the small intestine. READ MORE

The LDB3 gene provides instructions for making a protein that is found in heart (cardiac) muscle and in the muscles used for movement (skeletal muscle). Within muscle fibers, structures called sarcomeres generate the force needed for muscles to contr READ MORE

The LDHA gene provides instructions for making a protein called lactate dehydrogenase-A, which is one piece (subunit) of the lactate dehydrogenase enzyme. There are five different forms of this enzyme, each made up of four protein subunits. Various c READ MORE

The LDHB gene provides instructions for making a protein called lactate dehydrogenase-B, which is one piece (subunit) of the lactate dehydrogenase enzyme. There are five different forms of this enzyme, each made up of four protein subunits. Various c READ MORE

The LDLR gene provides instructions for making a protein called the low-density lipoprotein receptor. This receptor binds to particles called low-density lipoproteins (LDLs), which are the primary carriers of cholesterol in the blood. Cholesterol is READ MORE

The LDLRAP1 gene (also known as ARH ) provides instructions for making a protein that helps remove cholesterol from the bloodstream. Cholesterol is a waxy, fat-like substance that is produced in the body and obtained from foods that come from animals READ MORE

The LEMD3 gene provides instructions for making a protein that is located in a cell structure called the nuclear envelope. The nuclear envelope surrounds the nucleus, acting as a barrier between the nucleus and the rest of the cell. The LEMD3 protein READ MORE
