General annotation (Comments)

Function

Catalyzes intramembrane proteolysis of some signal peptides after they have been cleaved from a preprotein, resulting in the release of the fragment from the ER membrane into the cytoplasm. Required to generate lymphocyte cell surface (HLA-E) epitopes derived from MHC class I signal peptides. May play a role in graft rejection By similarity. May be necessary for the removal of the signal peptide that remains attached to the hepatitis C virus core protein after the initial proteolytic processing of the polyprotein.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.

Tissue specificity

Widely expressed with highest levels in kidney, liver, placenta, heart, lung, leukocytes and small intestine. Expressed abundantly in the CNS with highest levels in thalamus and medulla. Ref.2

Post-translational modification

N-glycosylated. Ref.1 Ref.14

Sequence similarities

Belongs to the peptidase A22B family.

Sequence caution

The sequence AAQ13609.1 differs from that shown. Reason: Frameshift at positions 320, 329, 330 and 358.

The sequence BAC11138.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention.

The sequence CAI19152.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAI20173.1 differs from that shown. Reason: Erroneous gene model prediction.
