Cd40lg - CD40 ligand

Predicted to enable CD40 receptor binding activity and integrin binding activity. Involved in isotype switching. Acts upstream of or within B cell differentiation and regulation of immunoglobulin production. Located in external side of plasma membrane. Is expressed in Meckel's cartilage; dorsal root ganglion; and limb. Used to study inflammatory bowel disease and systemic lupus erythematosus. Human ortholog(s) of this gene implicated in several diseases, including Kawasaki disease; artery disease (multiple); autoimmune disease (multiple); combined T cell and B cell immunodeficiency (multiple); and hematologic cancer (multiple). Orthologous to human CD40LG (CD40 ligand). [provided by Alliance of Genome Resources, Apr 2022]
