Proapoptotic B-cell lymphoma 2 (BCL-2) antagonist/killer (BAK) and BCL-2-associated X (BAX) form toxic mitochondrial pores in response to cellular stress. Whereas BAX resides predominantly in the cytosol, BAK is constitutively localized to the outer mitochondrial membrane. Select BCL-2 homology domain 3 (BH3) helices activate BAX directly by engaging an α1/α6 trigger site. The inability to expr...

The results of modeling of a novel human histone acetyltransferase Patt1 are presented here. This protein belongs to the GNAT GCN5 family and shows proapoptotic activity in human hepatocellular carcinoma cells. Patt1 is an attractive therapeutic target. The sequence analysis, fold recognition predictions and homology modeling of Patt1 protein structure were performed. N- and C- termini of Patt1...

  Background and Objective: As apoptotic cell death is extremely involved in physiological development and many pathological situations such as cancer and neurodegenerative diseases, the understanding of its molecular machinery can be useful in designing new therapeutic strategies. The present study investigated the temporal expression of the proapoptotic protein Bax in adult spinal motoneuron...
