Facts about Fas apoptotic inhibitory molecule 3.
Seems to activate an inhibitory pathway that prevents CASP8 activation after FAS stimulation, rather than blocking apoptotic signals downstream. May inhibit FAS-induced apoptosis by preventing CASP8 processing through CFLAR up-regulation.

Expressed in lymph nodes, peripheral blood leukocytes, lung, thymus and kidneys. Very weak expression detected in spleen, liver, heart, and salivary gland. Expressed in lymphoid cell lines such as Jurkat, CEM-T4, MOLT-4, HB11;19 and Reh. No expression detected in nonhematopoietic cell lines including Hep-G2, HEK293 and HeLa. Detected at high levels in chronic lymphocytic leukemia cells.
[Isoform 1]: Membrane; Single-pass membrane protein.; [Isoform 3]: Secreted. Detected in the serum.
