Function

Involved in the modulation of the mitochondrial apoptotic pathway by ensuring the accumulation of cardiolipin (CL) in mitochondrial membranes. In vitro, the TRIAP1:PRELID1 complex mediates the transfer of phosphatidic acid (PA) between liposomes and probbaly functions as a PA transporter across the mitochondrion intermembrane space to provide PA for CL synthesis in the inner membrane. Mediates cell survival by inhibiting activation of caspase-9 which prevents induction of apoptosis (By similarity). {ECO:0000250}.

Subcellular Localization

Cytoplasm, perinuclear region {ECO:0000250}. Mitochondrion intermembrane space.
