Trap1 Antibody: RPE

The 90 kDa heat shock protein (HSP90) family of proteins that play an important physiological role. HSP90 is involved in numerous cellular processes but is best known for its association with signal transduction machinery. A recently cloned homolog of HSP90 is the tumor necrosis factor receptor-associated protein (TRAP1). Like HSP90, TRAP1 is found to be associated with numerous proteins involved in diverse actions (1, 2). Immunofluorescence data has shown TRAP1 to be localized in the mitochondria of mammalian cells. This observation and the fact that TRAP1 is shown to have a mitochondrial targeting pre-sequence strongly implicates TRAP1 as a mitochondrial matrix protein (3).

1 µg/ml of SMC-207 was sufficient for detection of Trap-1/HSP75 in 20 µg of Human A431 lysate by ECL immunoblot analysis using Goat anti-rabbit IgG:HRP as the secondary antibody.
