CELA2B

CELA2B is a gene that encodes the protein elastase 2B, a member of the elastase family of serine proteases. This protein is primarily expressed in the pancreas and plays a crucial role in the process of digestion.

Function

The CELA2B gene is responsible for the production of the elastase 2B enzyme. This enzyme is a type of protease, which means it breaks down proteins in the body. Specifically, elastase 2B is involved in the digestion of food in the small intestine. It breaks down proteins into smaller amino acids that can be absorbed and used by the body.

Clinical Significance

Mutations in the CELA2B gene can lead to various health conditions. For instance, a deficiency in the elastase 2B enzyme can result in malabsorption syndrome, a condition where the small intestine cannot absorb nutrients from food properly. This can lead to malnutrition and weight loss.

Research

Research into the CELA2B gene and its associated protein is ongoing. Understanding the function and regulation of this gene could provide insights into digestive disorders and potential treatments.
