abstract = {Signal peptide peptidase (SPP) is an ER-resident aspartyl
intramembrane protease cleaving proteins within type
II-oriented transmembrane segments. Here, we identified the
tail-anchored protein Three prime repair exonuclease 1
(TREX1) as a novel substrate of SPP. Based on its DNase
activity, TREX1 removes cytosolic DNA acting as a negative
regulator of the DNA-sensing cGAS/STING pathway. TREX1
loss-of-function variants cause Aicardi-Goutières syndrome
(AGS), a type I interferonopathy. Cleavage of ER-bound TREX1
by SPP releases a cleavage product into the cytosol.
Proteolysis depends on sequence determinants within the
transmembrane segment and is modulated by different
disease-associated TREX1 variants. The AGS-causing T303P
variant greatly enhanced susceptibility of TREX1 to
intramembrane cleavage accounting for increased degradation
and reduced protein stability in AGS patients homozygous for
this variant. Other variants within the TREX1 transmembrane
segment, P290L, Y305C and G306A, associated with systemic
lupus erythematosus variably modulated TREX1 proteolytic
processing. Altogether, intramembrane proteolysis can act as
a regulator of TREX1 both by controlling its cytosolic
localization and mediating its turnover with implications
for disease pathogenesis.},
