CC   -!- FUNCTION: Negative regulator of amyloid-beta peptide production. May
CC       inhibit the processing of APP by blocking its access to alpha- and
CC       beta-secretase. Binding to the beta-secretase-cleaved APP C-terminal
CC       fragment is negligible, suggesting that ITM2C is a poor gamma-secretase
CC       cleavage inhibitor. May play a role in TNF-induced cell death and
CC       neuronal differentiation (By similarity). {ECO:0000250,
CC       ECO:0000269|PubMed:18452648, ECO:0000269|PubMed:19366692}.
CC   -!- SUBUNIT: Interacts with BACE1. Interacts with APP. Interacts with

CC       Name=3;
CC         IsoId=Q9NQX7-3; Sequence=VSP_013472;
CC   -!- TISSUE SPECIFICITY: High levels in the brain, specifically in the
CC       cerebral cortex, medulla, amygdala, hippocampus, thalamus, caudate
CC       nucleus, cerebellum, olfactory lobe and spinal cord. Very low levels in
CC       other organs. {ECO:0000269|PubMed:11290423,
CC       ECO:0000269|PubMed:15606899}.
CC   -!- PTM: Type I membrane-bound, as well as soluble, furin has a pre-eminent
CC       role in ITM2C proteolytic processing. PCSK7 and PCSK5 may also be
CC       involved although to a lesser extent. The soluble form of PCSK7 is
CC       incapable of processing ITM2C. Fails to undergo shedding by ADAM10 and
CC       intramembrane cleavage by SPPL2B. {ECO:0000269|PubMed:15606899}.
CC   -!- SIMILARITY: Belongs to the ITM2 family. {ECO:0000305}.
