The SEC23B gene provides instructions for making one component of a large group of interacting proteins called coat protein complex II (COPII). COPII is involved in the formation of vesicles, which are small, sac-like structures that transport protei READ MORE

The SELENON gene (also called SEPN1 ) provides instructions for making a protein called selenoprotein N. This protein is part of a family of selenoproteins, which have several critical functions within the body. Selenoproteins are primarily involved READ MORE

The SEPSECS gene provides instructions for making an enzyme known as SepSecS. This enzyme is involved in the formation of a molecule called a transfer RNA (tRNA), which is a chemical cousin of DNA that is needed for building proteins. This particular READ MORE

The SEPTIN9 gene provides instructions for making a protein called septin-9, which belongs to a group of proteins called septins. Septins are involved in a process called cytokinesis, which is the step in cell division when the fluid inside the cell READ MORE

The SERAC1 gene provides instructions for making a protein whose function is not completely understood. Studies suggest that the SERAC1 protein is involved in altering (remodeling) certain fats called phospholipids, particularly a phospholipid called READ MORE

The SERPINA1 gene provides instructions for making a protein called alpha-1 antitrypsin, which is a type of serine protease inhibitor (serpin). Serpins help control several types of chemical reactions by blocking (inhibiting) the activity of certain READ MORE

The SERPINA6 gene provides instructions for making a protein called corticosteroid-binding globulin (CBG), which is primarily produced in the liver. The CBG protein attaches (binds) to a hormone called cortisol, which has numerous functions, such as READ MORE

The SERPINA7 gene provides instructions for making a protein called thyroxine-binding globulin. This protein attaches (binds) to hormones made by the thyroid gland, which is a butterfly-shaped tissue in the lower neck. Thyroid hormones play an import READ MORE

The SERPINC1 gene provides instructions for making a protein called antithrombin (previously known as antithrombin III), which is a type of serine protease inhibitor (serpin). Serpins help control several types of chemical reactions by blocking the a READ MORE

The SERPINE1 gene provides instructions for making a protein called plasminogen activator inhibitor 1 (PAI-1). PAI-1 is involved in normal blood clotting (hemostasis). After an injury, clots protect the body by sealing off damaged blood vessels and p READ MORE
