The SGCG gene provides instructions for making the gamma component (subunit) of a group of proteins called the sarcoglycan protein complex. The sarcoglycan protein complex is located in the membrane surrounding muscle cells. It helps maintain the str READ MORE

The SGO1 gene provides instructions for making part of a protein complex called cohesin. This protein complex helps control the placement of chromosomes during cell division. Before cells divide, they must copy all of their chromosomes. The copied DN READ MORE

The SGSH gene provides instructions for producing an enzyme called sulfamidase. This enzyme is located in lysosomes, compartments within cells that digest and recycle different types of molecules. Sulfamidase is involved in the step-wise breakdown of READ MORE

The SH2D1A gene provides instructions for making a protein called signaling lymphocyte activation molecule (SLAM) associated protein (SAP). SAP interacts with other proteins called SLAM family receptors to activate signaling pathways that are involve READ MORE

The SH3BP2 gene provides instructions for making a protein whose exact function is unclear, although it is known to interact with other proteins within cells. The SH3BP2 protein plays a role in transmitting chemical signals, particularly in certain i READ MORE

The SHANK3 gene provides instructions for making a protein that is found in many of the body's tissues but is most abundant in the brain. The SHANK3 protein plays a role in the functioning of synapses, which are the connections between nerve cells (n READ MORE

The SHH gene provides instructions for making a protein called Sonic Hedgehog. This protein functions as a chemical signal that is essential for embryonic development. Sonic Hedgehog plays a role in cell growth, cell specialization, and the normal sh READ MORE

The SHOX gene provides instructions for making a protein that regulates the activity of other genes. On the basis of this role, the SHOX protein is called a transcription factor. The SHOX gene is part of a large family of homeobox genes, which act du READ MORE

The SI gene provides instructions for producing the enzyme sucrase-isomaltase. This enzyme is made in the cells that line the small intestine, where it is involved in breaking down the sugars sucrose (a sugar found in fruits, and also known as table READ MORE

The SIL1 gene provides instructions for producing a protein located in a cell structure called the endoplasmic reticulum. Among its many functions, the endoplasmic reticulum folds and modifies newly formed proteins so they have the correct 3-dimensio READ MORE

The SIX1 gene is part of a group of similar genes known as the SIX gene family. Genes in this family provide instructions for making proteins that bind to DNA and control the activity of other genes. Based on this role, SIX proteins are called transc READ MORE

The SIX3 gene provides instructions for making a protein that plays an important role in the development of the eyes and front part of the brain (forebrain). This protein is a transcription factor, which means that it attaches (binds) to specific reg READ MORE
