Abstract excerpt
The signal peptide peptidase (SPP) is an intramembrane-cleaving aspartyl protease that acts on type II transmembrane proteins. SPP substrates include signal peptides after they have been cleaved from a preprotein, hence the name. The known SPP isoform, which we renamed SPPalpha, contains an endoplasmic reticulum retention signal at the carboxy terminus. We found a new splice variant, SPPbeta, with an additional...
