ID:NAA15_HUMAN DESCRIPTION: RecName: Full=N-alpha-acetyltransferase 15, NatA auxiliary subunit; AltName: Full=Gastric cancer antigen Ga19; AltName: Full=N-terminal acetyltransferase; AltName: Full=NMDA receptor-regulated protein 1; AltName: Full=Protein tubedown-1; AltName: Full=Tbdn100; FUNCTION: The NAA10-NAA15 complex displays alpha (N-terminal) acetyltransferase activity that may be important for vascular, hematopoietic and neuronal growth and development. Required to control retinal neovascularization in adult ocular endothelial cells. In complex with XRCC6 and XRCC5 (Ku80), up-regulates transcription from the osteocalcin promoter. SUBUNIT: Interacts with NAA10, XRCC6, NAA50 and XRCC5. SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Mainly cytoplasmic, nuclear in some cases. Present in the free cytosolic and cytoskeleton-bound polysomes, but not in the membrane-bound polysomes. TISSUE SPECIFICITY: Expressed at high levels in testis and in ocular endothelial cells. Also found in brain (corpus callosum), heart, colon, bone marrow and at lower levels in most adult tissues, including thyroid, liver, pancreas, mammary and salivary glands, lung, ovary, urogenital system and upper gastrointestinal tract. Overexpressed in gastric cancer, in papillary thyroid carcinomas and in a Burkitt lymphoma cell line (Daudi). Specifically suppressed in abnormal proliferating blood vessels in eyes of patients with proliferative diabetic retinopathy. PTM: Cleaved by caspases during apoptosis, resulting in a stable 35 kDa fragment. SIMILARITY: Contains 8 TPR repeats. SEQUENCE CAUTION: Sequence=AAH39818.1; Type=Miscellaneous discrepancy; Note=Contaminating sequence. Potential poly-A sequence;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
