RAG1 : recombination activating 1

The RAG1 Gene and Its Vital Role in Immune System Development

Description:

The RAG1 gene is responsible for encoding a crucial component of the RAG complex, a protein assembly essential for the proper functioning of the immune system. This complex plays a critical role in a process called V(D)J recombination, which generates the enormous diversity of antigen receptors on B cells and T cells, enabling the recognition and combat of a vast array of foreign invaders.

Associated Diseases:

Mutations or dysregulation of the RAG1 gene can lead to severe immunodeficiency disorders, affecting T and B cell development and function. One such disorder is Omenn syndrome, characterized by a profound lack of T and B cells, resulting in life-threatening infections and autoimmune complications.

Did you Know ?

The V(D)J recombination process, facilitated by the RAG complex, generates an estimated 10¹⁵ different antigen receptors in humans. This staggering variability ensures the immune system‘s remarkable ability to recognize and respond to countless potential pathogens.
