The MYBPC1 gene provides instructions for making one version of a protein called myosin binding protein C. Several versions of myosin binding protein C are produced from different genes; these proteins are found in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. The version produced from the MYBPC1 gene, which is known as the slow skeletal isoform, is found primarily in skeletal muscles.

The MYBPC1 gene provides instructions for making one version of a protein called myosin binding protein C. Several versions of myosin binding protein C are produced from different genes; these proteins are found in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. The version produced from the MYBPC1 gene, which is known as the slow skeletal isoform, is found primarily in skeletal muscles.
The slow isoform of myosin binding protein C is active during the development of skeletal muscles. Researchers believe that this protein helps regulate the tensing of muscle fibers (muscle contraction). Myosin binding protein C interacts with other muscle proteins, including myosin, actin, and titin. These proteins play essential roles in muscle cell structures called sarcomeres, which generate the mechanical force needed for muscles to contract. Studies suggest that myosin binding protein C contributes to the stability and maintenance of sarcomeres.

The immune system
This leaflet gives a brief overview of the immune system and how it works. A person with a weak immune system might have difficulty fighting off infections. In autoimmune diseases the body is unable to tell what is its own and what is foreign, so it attacks itself. Autoimmune diseases can attack any part of the body - eg, type 1 diabetes.

Wilson's disease
Wilson's disease is a genetic disorder in which copper builds up in the body, mainly in the liver and brain. Without any treatment, the build-up of copper can cause serious symptoms. Treatment is with medication to remove the excess copper and/or to prevent a further build-up of copper. What is Wilson's disease. Wilson's disease is a condition.

Nephrotic syndrome
Nephrotic syndrome is a condition where the 'filters' in the kidney become 'leaky' and large amounts of protein leak from the blood into the urine. The main symptom is fluid retention (oedema) which is mainly due to the low protein level in the blood. Various diseases can cause nephrotic syndrome, some more serious than others. Nephrotic syndrome.

Primary biliary cholangitis
Primary biliary cholangitis (PBC) is a condition that slowly damages the bile ducts in your liver, leading to liver damage and, sometimes, liver scarring (cirrhosis). Primary biliary cholangitis (PBC) is an auto-immune condition in which your immune system gradually destroys the tiny tubes (bile ducts) which take bile from the liver to the gut.
