Impairment of protein ubiquitination may cause delayed neuronal death
The hippocampus is a brain structure specifically vulnerable to short periods of transient cerebral ischemia, and which displays delayed neuronal necrosis. Protein ubiquitination is a posttranslational modification of proteins and an important factor in heat shock response and a regulator of ATP-dependent protein degradation. Using affinity purified antibodies against ubiquitin and ubiquitin-prote
