APO-1 (Fas/CD95), a member of the tumor necrosis factor receptor superfamily, induces apoptosis upon receptor oligomerization. In a search to identify intracellular signaling molecules coupling to oligomerized APO-1, several cytotoxicity-dependent APO-1-associated proteins (CAP) were immunoprecipitated from the apoptosis-sensitive human leukemic T cell line HUT78 and the lymphoblastoid B cell line SKW6.4. CAP1-3 (27-29 kDa) and CAP4 (55 kDa), instantly detectable after the crosslinking of APO-1, were associated only with aggregated (the signaling form of APO-1) and not with monomeric APO-1. CAP1 and CAP2 were identified as serine phosphorylated MORT1/FADD. The association of CAP1-4 with APO-1 was not observed with C-terminally truncated non-signaling APO-1. In addition, CAP1 and CAP2 did not associate with an APO-1 cytoplasmic tail carrying the lprcg amino acid replacement. Moreover, no APO-1-CAP association was found in the APO-1+, anti-APO-1-resistant pre-B cell line Boe. Our data suggest that in vivo CAP1-4 are the APO-1 apoptosis-transducing molecules. [less ▲]

APO-1/Fas (CD95) is a type 1 transmembrane protein that belongs to the tumor necrosis factor/nerve growth factor receptor family characterized by cysteine-rich extracellular domains. Cross-linking of APO-1 mediates apoptosis in a variety of cells. In the present study we report the isolation and characterization of the human APO-1 gene spanning approximately 25 kb of human chromosome 10. The gene consists of nine exons (25 bp to > 1.44 kb) separated by eight introns (152 bp to approximately 12 kb). The boundaries of exon 2 to 5 encoding the extracellular region do not match the boundaries of the three APO-1 protein subdomains. Exon structure and functional protein domains correspond for exon 6 encoding the transmembrane region and for exon 9 encoding the "death domain". By a polymerase chain reaction-based approach we localized major transcriptional start sites in human spleen cells 77 and 73 nucleotides upstream of the translation initiation codon of the human APO-1 gene. Minor initiation sites were found at positions -128, -111, -91, and -74. The 5' flanking sequence of the human APO-1 gene is GC rich, contains a high number of CpG dinucleotides and lacks a consensus TATA box. Consensus binding sites for the transcription factors Sp1, AP-1, AP-2, GAF, NF-kappa B, and NF-AT were found. The elucidation of the human APO-1 gene structure will facilitate the study of its involvement in various diseases such as in autoimmunity. [less ▲]

Apoptosis in T and B lymphocytes is involved in all fundamental processes in the immune system. It is a mechanism to regulate the course of an immune response and to establish immunological memory as well as central and peripheral tolerance. Apoptosis in lymphocytes is regulated by gene products that induce or block this process. Elucidating the molecular basis for sensitivity and resistance towards induction of apoptosis is the key to the understanding of the development of the immune system, basic immune reactions and the pathogenesis of autoimmune diseases, AIDS and cancer.
