Three functional soluble forms of the human apoptosis-inducing Fas molecule are produced by alternative splicing.
Abstract
Fas/Apo-1 molecule is an apoptosis-signaling cell surface Ag belonging to the TNFR family. To investigate the possibility that soluble forms of the Fas receptor are expressed in human cells, we analyzed Fas mRNA transcripts obtained from activated peripheral mononuclear cells of healthy donors and from human tumor cell lines. We identified and characterized three human mRNA Fas variants: FasTMDel, FasDel2, and FasDel3. To determine whether the three transcripts were derived by alternative splicing, the Fas genomic intron/exon organization of the regions surrounding the deleted sequences was analyzed in Fas clones isolated from a human genomic library. Expression of the transcripts was studied in COS cells transiently transfected with the FasTMDel, FasDel2, and FasDel3 cDNAs. Immunocytochemical and in vitro apoptosis inhibition studies suggest that the transcripts are expressed as soluble Fas proteins that may play a functional role in the regulation of apoptosis.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
