Kim et al. reported that CypB protects cells against ER stress-induced cell death at least partly through blocking the Ca2+ leakage from ER to cytosol [45]. Overexpression of CypB is associated with tumor progression through regulation of hormone receptor expression and gene products involved in cell proliferation and motility [46]. Interestingly, CypB possesses two antigenic epitopes (CypB (82-92) and CypB (91-99)) recognized by HLA-A24-restricted and tumor-specific cytotoxic T lymphocytes that are suggested to be used for vaccines against cancers [47]. CypC is another Cyp family member that is primarily located in ER, but

its role remains to be determined. CypC can form a complex with the COOH-terminal fragment of osteopontin. This complex binds to CD147 to activate Akt1/2 and MMP-2 in 4T07 murine breast cancer cells. This CyC- osteopontin complex regulates in vitro migration and invasion properties of 4T1 and 4T07 breast cancer cells [48]. CypD is an important component of the mitochondrial permeability transition pore, another components of which are the voltage-dependent outer membrane Fludarabine anion channel, adenine nucleotide translocator [49, 50], and hexokinase. PPIase activity of CypD may be necessary for binding of CypD to the MPTP complex [51]. Although function of CypD in mitochondria is controversial, overexpression of CypD attenuates sensitivity of HEK 293 and rat glioma C6 cells to apoptotic stimuli, with protective effects of CypD requiring PPIase activity [52]. Consistently, several reports have shown that CypD is overexpressed and has an anti-apoptotic effect in various tumors via a Bcl 2 collaborator and an inhibitor of cytochrome c release from mitochondria [53].
