BZRAP1-AS1
B-Cell Receptor Associated Protein 1 (BZRAP1)
Description
BZRAP1 is a protein found on the surface of B cells, a type of white blood cell responsible for producing antibodies. It plays a crucial role in regulating B cell activation and antibody production, which are essential for the immune system to fight infections.
BZRAP1 is part of a signaling complex that includes the B cell receptor (BCR) and other molecules. When a B cell encounters an antigen, the BCR binds to the antigen and triggers a cascade of signaling events that involve BZRAP1. This signaling leads to B cell activation and differentiation into antibody-producing plasma cells.
Associated Diseases
Mutations or defects in BZRAP1 have been associated with several autoimmune and immunodeficiency diseases, including:
- Common variable immunodeficiency (CVID): A disorder characterized by recurrent infections due to low levels of antibodies
- Selective IgA deficiency: A condition in which the immune system produces little or no IgA antibodies
- Autoimmune lymphoproliferative syndrome (ALPS): A rare disorder that leads to autoimmune diseases and lymphoma
- Evans syndrome: An autoimmune disorder that affects blood platelets and red blood cells
Did you Know ?
Studies have shown that mutations in the BZRAP1 gene are found in approximately 1-5% of patients with CVID, making it one of the most common genetic causes of this disorder.
