Protein Structure
UniProt Annotation
Function Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta- amyloid precursor protein). It probably represents a stabilizing cofactor required for the assembly of the gamma-secretase complex.
Subcellular Localization Membrane {ECO:0000305}; Single-pass type I membrane protein {ECO:0000305}. Melanosome {ECO:0000269PubMed:12643545, ECO:0000269PubMed:17081065}. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
Disease Associations Acne inversa, familial, 1 (ACNINV1) [MIM:142690]: A chronic relapsing inflammatory disease of the hair follicles characterized by recurrent draining sinuses, painful skin abscesses, and disfiguring scars. Manifestations typically appear after puberty. {ECO:0000269PubMed:20929727, ECO:0000269PubMed:21430701, ECO:0000269PubMed:21495993}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Widely expressed. {ECO:0000269PubMed:11396676}.
