The TWNK gene provides instructions for making two very similar proteins called Twinkle and Twinky. These proteins are found in the mitochondria, which are structures in which a process called oxidative phosphorylation occurs to convert the energy fr READ MORE

The TWIST1 gene provides instructions for making a protein that plays an important role in early development. This protein is a transcription factor, which means that it attaches (binds) to specific regions of DNA and controls the activity of particu READ MORE

The TUBB4A gene provides instructions for making a protein called beta-tubulin (β-tubulin). This protein is part of the tubulin family of proteins that form and organize structures called microtubules. Microtubules are rigid, hollow fibers that make READ MORE

The TUBB3 gene provides instructions for making one version of a protein called beta-tubulin (β-tubulin). This protein is part of the tubulin family of proteins that form and organize cell structures called microtubules. Microtubules are rigid, hollo READ MORE

The TUBB2B gene provides instructions for making one version of a protein called beta-tubulin (β-tubulin). This protein is part of the tubulin family of proteins that form and organize cell structures called microtubules. Microtubules are rigid, holl READ MORE

The TUBA1A gene provides instructions for making a protein called alpha-tubulin (α-tubulin). This protein is part of the tubulin family of proteins that form and organize structures called microtubules. Microtubules are rigid, hollow fibers that make READ MORE

The TTR gene provides instructions for making a protein called transthyretin. This protein transports vitamin A (retinol) and a hormone called thyroxine throughout the body. To transport thyroxine, four transthyretin proteins must attach (bind) to ea READ MORE

The TTPA gene provides instructions for making the α-tocopherol transfer protein (αTTP), which is found in the liver and brain. This protein controls the distribution of vitamin E obtained from the diet (also called α-tocopherol) to cells and tissues READ MORE

The TTN gene provides instructions for making a very large protein called titin. This protein plays an important role in skeletal muscles, which the body uses for movement, and in heart (cardiac) muscle. Slightly different versions (called isoforms) READ MORE

The TSPYL1 gene provides instructions for making a protein called TSPY-like 1. This protein is active in the brain, testes (in males), and other tissues, although its function is not well understood. TSPY-like 1 contains a region called a nucleosome READ MORE

The TSHR gene provides instructions for making a protein, known as a receptor, that attaches (binds) to a hormone called thyroid stimulating hormone (TSH). This receptor spans the membrane of certain cells (called follicular cells) in the thyroid gla READ MORE

The TSHB gene provides instructions for one piece (subunit) of a hormone called thyroid stimulating hormone (TSH). Thyroid stimulating hormone consists of two subunits called alpha and beta. The TSHB gene provides instructions for making the beta sub READ MORE
