TRIAP1 interacts with PRELID family proteins to facilitate phosphatidylserine (PS) and phosphatidic acid (PA) transport, critical for maintaining mitochondrial membrane integrity . Key findings include:
Antiapoptotic Activity: TRIAP1 overexpression inhibits cytochrome c release, reducing susceptibility to apoptosis under mild genotoxic stress .
p53 Pathway Interaction: Acts as a p53-responsive survival factor, antagonizing p21-mediated cell-cycle arrest .
Cancer Relevance: Elevated TRIAP1 levels correlate with tumorigenesis in colorectal cancer models, where its knockdown activates p53 and suppresses mTORC1 signaling .
Commercially available recombinant TRIAP1 proteins are optimized for research applications:
Studies using recombinant TRIAP1 have revealed:
