CD40L, Recombinant, Human, aa116-261, His-Tag (CD154, T Cell Antigen Gp39, TNF Related Activation Pr

The protein encoded by this gene is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. A defect in this gene results in an inability to undergo immunoglobulin class switch and is associated with hyper-IgM syndrome. [provided by RefSeq, Jul 2008].
