Prabhakar§ From the Department of Microbiology and Immunology, University of Illinois, Chicago, Illinois 60612 We identified a novel cDNA (IG20) that is homolo- cellular signal transduction by a diverse array of cytoplasmic gous to cDNAs encoding a protein differentially ex- adaptor proteins. Some of these adaptor proteins contain a pressed in normal and neoplastic cells (DENN-SV) and death domain through which they interact with the cytoplas- human MADD (MAPK-activating death domain-con- mic death domain of TNFR1 (4 – 6). taining protein). Furthermore, we show that the above Previously, we and others identified some cDNAs that are variants most likely result from alternative splicing TI - Contrasting Effects of IG20 and Its Splice Isoforms, MADD and DENN-SV, on Tumor Necrosis Factor α-induced Apoptosis and Activation of Caspase-8 and -3 JF - Journal of Biological Chemistry DO - 10.1074/jbc.m104835200 DA - 2001-12-01 UR - https://www.deepdyve.com/lp/unpaywall/contrasting-effects-of-ig20-and-its-splice-isoforms-madd-and-denn-sv-0QcIb3FQNN DP - DeepDyve ER -
