General annotation (Comments)

Function	IFN-induced antiviral protein that mediate cellular innate immunity to at least three major human pathogens, namely influenza A H1N1 virus, West Nile virus, and dengue virus by inhibiting the early step(s) of replication. Plays a key role in the antiproliferative action of IFN-gamma either by inhibiting the ERK activition or by arresting cell growth in G1 phase in a p53-dependent manner. Implicated in the control of cell growth. Component of a multimeric complex involved in the transduction of antiproliferative and homotypic adhesion signals. Ref.5 Ref.7
Subunit structure	Interacts with CAV1; this interaction enhances the ability of CAV1 in inhibiting ERK activation. Ref.6
Subcellular location	Cell membrane; Multi-pass membrane protein Ref.6.
Induction	By IFN-alpha and IFNG/IFN-gamma.
Post-translational modification	Palmitoylation on membrane-proximal cysteines controls clustering in membrane compartments and antiviral activity against influenza virus By similarity.
Sequence similarities	Belongs to the CD225 family.
