The PSENEN gene provides instructions for making a protein called gamma-secretase subunit PEN-2 (shortened to PEN-2). This protein is one part (subunit) of a complex called gamma- (γ-) secretase. PEN-2 processes another subunit of the complex, presenilin 1, which is produced from the PSEN1 gene. This step is necessary for the γ-secretase complex to be functional.
Normal function
The PSENEN gene provides instructions for making a protein called gamma-secretase subunit PEN-2 (shortened to PEN-2). This protein is one part (subunit) of a complex called gamma- (γ-) secretase. PEN-2 processes another subunit of the complex, presenilin 1, which is produced from the PSEN1 gene. This step is necessary for the γ-secretase complex to be functional.
The γ-secretase complex is located in the membrane that surrounds cells, where it cuts apart (cleaves) many different proteins that span the cell membrane (transmembrane proteins). This cleavage is an important step in several chemical signaling pathways that transmit signals from outside the cell into the nucleus. One of these pathways, known as Notch signaling, is essential for the normal maturation and division of hair follicle cells and other types of skin cells. Notch signaling is also involved in normal immune system function.

Alcohol, tobacco and caffeine can be classed as recreational drugs but are not covered in this leaflet. Recreational drugs are usually started to provide pleasure, or improve life in some way. However, they can lead to addiction, to health and social problems and to crime. Most are illegal, so their use comes with all the consequences of breaking.

Tuberculosis
If you have symptoms, or a doctor can find signs of the infection when examining you, this is known as active tuberculosis. If you have TB infection without any signs or symptoms, this is known as latent TB. The number of people with active TB was at an all-time low in the UK in the early 1980s but the number of cases has since increased. In the.
