LARD: a new lymphoid-specific death domain containing receptor regulated by alternative pre-mRNA splicing.

ABSTRACT: Fas and TNF-R1 are cysteine-rich cell surface receptors related to the low-affinity nerve growth factor receptor family. Engagement of these receptors by their respective ligands, FasL and tumor necrosis factor, leads to apoptosis that is signaled through a conserved intracellular portion of the receptor termed the "death domain." We have cloned a new member of this family, lymphocyte-associated receptor of death (LARD), which leads to spontaneous apoptosis when expressed in 293T cells. The expression of LARD is more tightly regulated than that of either Fas or TNF-R1 as it is found predominantly on lymphocytes (T and B cells) but not on macrophages or a number of transformed lymphocyte cell lines. Alternative pre-mRNA splicing generates at least 11 distinct isoforms of LARD. The full-leng
