Target
-
Function
Receptor for TNFSF5/CD40LG. -
Tissue specificity
B-cells and in primary carcinomas. -
Involvement in disease
Defects in CD40 are the cause of hyper-IgM immunodeficiency syndrome type 3 (HIGM3) [MIM:606843]; also known as hyper-IgM syndrome 3. HIGM3 is an autosomal recessive disorder which includes an inability of B cells to undergo isotype switching, one of the final differentiation steps in the humoral immune system, an inability to mount an antibody-specific immune response, and a lack of germinal center formation. -
Sequence similarities
Contains 4 TNFR-Cys repeats. -
Cellular localization
Secreted and Cell membrane. - Information by UniProt
