The CREBBP gene provides instructions for making CREB binding protein, which regulates the activity of many genes in tissues throughout the body. This protein plays an essential role in controlling cell growth and division and prompting cells to mature and assume specialized functions (differentiate). CREB binding protein appears to be critical for normal development before and after birth. Studies show that this protein is involved in development of the brain and may also be involved in the formation of long-term memories.
Normal function
The CREBBP gene provides instructions for making CREB binding protein, which regulates the activity of many genes in tissues throughout the body. This protein plays an essential role in controlling cell growth and division and prompting cells to mature and assume specialized functions (differentiate). CREB binding protein appears to be critical for normal development before and after birth. Studies show that this protein is involved in development of the brain and may also be involved in the formation of long-term memories.
CREB binding protein carries out its functions by turning on (activating) transcription, which is the first step in the production of proteins from the instructions stored in DNA. The CREB binding protein ensures the DNA is ready for transcription by attaching a small molecule called an acetyl group to proteins called histones (a process called acetylation). Histones are structural proteins that bind DNA and give chromosomes their shape. Acetylation of the histone changes the shape of the chromosome, making genes available for transcription. On the basis of this function, CREB binding protein is called a histone acetyltransferase.
In addition, CREB binding protein connects other proteins that start the transcription process (known as transcription factors) with the group of proteins that carries out transcription. On the basis of this function, CREB binding protein is called a transcriptional coactivator.

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.

Pemphigus vulgaris
Pemphigus vulgaris is a very serious skin disease that causes blisters. It is rare. Pemphigus vulgaris is more serious than most other blistering skin conditions. These different conditions vary grea... Pemphigus vulgaris is the most common form of pemphigus and one of the most serious blistering skin conditions. This leaflet is only about.
Patient information leaflet
Pompholyx
Pompholyx is a type of eczema where there are itchy blisters on the hands and feet, followed by inflamed and dry skin. The condition is usually long-term, with symptoms that come and go at various times. The first step in managing pompholyx is to identify and avoid things that make it worse. Treatment includes creams and ointments to reduce.
Patient information leaflet
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.
