Secondary Information

Protein Function  inhibit Fas-induced cell death.FAIM1 inhibits Fas ligand- and tumor necrosis factor alpha-induced apoptosis by direct interaction with Fas receptor and through the stabilization of levels of X-linked inhibitor of apoptosis protein, a potent anti-apoptotic protein that inhibits caspases..protect neurons from DR(death receptor)-induced apoptosis and are involved in neurite outgrowth and neuronal plasticity.
Biochemical Properties 20 kDa evolutionary-conserved soluble protein. it contains two independently folding domains. The short isoform, FAIM-S, was first isolated from B-lymphocytes as a protein that conferred resistance to Fas-induced cell death.a longer splice variant that contains 22 additional amino acids on the N-terminal end of the protein was identified and named FAIM-L .the C-terminal domain of FAIM-S folds as a non-conventional β-sandwich, and the crystal structure of the N-terminal domain revealed a similar conformation containing eight antiparallel β-strands
Site(s) of PTM(s)

N-glycosylation, O-glycosylation,
Predicted Disorder Regions 1-19, 177-182, 199-201
DisProt Annotation
TM Helix Prediction No TM helices
Additional Comments Low FAIM1 levels are found in Alzheimer's disease, thus sensitizing neurons to tumor necrosis factor alpha and prompting neuronal loss.
