Protein Structure

UniProt Annotation

Function

Acts as an A-kinase anchoring protein by binding to the type II regulatory subunit of protein kinase A and anchoring it to the mitochondrion. Also involved in synchronization of mitochondrial fission. Plays a role in the maturation of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis. {ECO:0000269PubMed:12186851, ECO:0000269PubMed:21255211}.

Subcellular Localization

Mitochondrion. Cytoplasmic vesicle, phagosome. Cytoplasmic vesicle, phagosome membrane {ECO:0000250}; Lipid-anchor {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Note=Recruited to phagosomes containing S.aureus or M.tuberculosis.

Disease Associations

Tissue Specificity

Widely expressed with high levels in heart, liver, kidney, bone marrow, testis, colon and fetal lung. {ECO:0000269PubMed:11784320, ECO:0000269PubMed:12186851}.
