text	pro-apoptotic protein located in the small subunit of the ribosome (Miller 2008)
	detected in the cytosol and mitochondria fraction, but only a little in the nucleus fraction in the cells before anti-CD3 antibody stimulation (Tosa 2010)
	specifically localizes in the mitochondrial matrix

basic FUNCTION	involved in mediating interferon-gamma induced cell death
	potential regulatory function of mitochondrial DAP3 involved in cellular senescence (Murata 2006)
	GTP-binding constituent of the small subunit of the mitochondrial ribosome with a pro-apoptotic function (Jacques 2009)
	mitochondrial ribosomal small subunit protein, which is a novel phosphorylated target (Miller 2008)
	may participate in mitochondrial maintenance and play a role in the balance between mitochondrial homoeostasis and tumourigenesis (Jacques 2009)
	responsible for regulating apoptosis induced by various stimuli (Harada 2010)
	critical for anoikis induction (detachment of adherent epithelial cells from the extracellular matrix inducing apoptosis) (Li 2009)
	critical for TCR-mediated induction of apoptosis at the downstream of NNR4A1 (Tosa 2010)
	DAP3 plays likely important roles in mitochondrial function and dynamics
	coordinates splicing regulatory networks, not only via mediating the formation of ribonucleoprotein complexes to induce substrate-specific splicing changes, but also via modulating splicing of numerous splicing factors to cause indirect effect on splicing
	can influence mitochondrial fission by modulating dynamin-related protein phosphorylation

component of mitochondrial ribosome

INTERACTION

DNA

RNA

small molecule

protein	may be interacting with MRPS27
	interacting with the glycocorticoid receptor and enhancing its ligand-induced activiry
	DAP3-binding protein termed death ligand signal enhancer (Harada 2010)
	interferon-beta promoter stimulator 1 (MAVS) binds DAP3 and induces anoikis by caspase activation (Li 2009)
	functionally associated with NR4A1 on TCR-mediated apoptosis (Tosa 2010)
	DAP3 mainly interacts with the deaminase domain of ADARB1 and represses editing via disrupting association of ADARB1 with its target transcripts
