The VHL gene provides instructions for making a protein that functions as part of a complex (a group of proteins that work together) called the VCB-CUL2 complex. This complex targets other proteins to be broken down (degraded) by the cell when they a READ MORE

The VDR gene provides instructions for making a receptor protein that helps the body use vitamin D. This vitamin can be obtained from food or made in the skin after exposure to the sun or to light from certain other sources, such as tanning beds. Vit READ MORE

The VCP gene provides instructions for making an enzyme called valosin-containing protein. This enzyme is found throughout the body and has a wide variety of functions within cells. It is involved in cell division, joining (fusing) membranes within c READ MORE

The VCAN gene provides instructions for making a protein called versican. Versican is a type of protein known as a proteoglycan, which means it has several sugar molecules attached to it. Versican is found in the extracellular matrix of many differen READ MORE

The UVSSA gene provides instructions for making a protein that is involved in repairing DNA damaged by ultraviolet (UV) rays from the sun. The damage can block vital cell activities such as gene transcription, which is the first step in protein produ READ MORE

The UTP4 gene provides instructions for making a protein called cirhin, whose precise function is unknown. This protein is found in many different tissues and organs. Within cells, cirhin is located in a structure called the nucleolus, which is a sma READ MORE

The USH2A gene provides instructions for making a protein called usherin. Usherin is an important component of basement membranes, which are thin, sheet-like structures that separate and support cells in many tissues. Usherin is found in basement mem READ MORE

The USB1 gene provides instructions for making an enzyme that functions as an RNA exonuclease. RNA exonucleases cut off (cleave) building blocks called nucleotides one at a time from molecules of RNA (a chemical cousin of DNA). This process helps sta READ MORE

The UROS gene provides instructions for making an enzyme known as uroporphyrinogen III synthase. This enzyme is involved in the production of a molecule called heme. Heme is vital for all of the body's organs, although it is most abundant in the bloo READ MORE

The UROD gene provides instructions for making an enzyme known as uroporphyrinogen decarboxylase. This enzyme is involved in the production of a molecule called heme. Heme is vital for all of the body's organs, although it is most abundant in the blo READ MORE

The UPB1 gene provides instructions for making an enzyme called beta-ureidopropionase. This enzyme is involved in the breakdown of molecules called pyrimidines, which are building blocks of DNA and its chemical cousin RNA. The beta-ureidopropionase e READ MORE

The UNC80 gene provides instructions for making a large protein that is important in the functioning of a sodium channel called NALCN. Sodium channels transport positively charged sodium atoms (sodium ions) into cells and play a key role in a cell's READ MORE
