Background Information

FAF1 was detected most abundant in testis, slightly less abundant in skeletal muscle and heart, followed by prostate, thymus, ovary, small intestine, and colon, but not in the peripheral blood leukocytes.The N-terminal region (amino acid 1∼201) including the upstream ubiquitin homology domain of hFAF1 could bind with the death domain of Fas, which mediates programmed cell death, also called apoptosis, in a number of organ systems, notably the immune and nervous systems.
