Immunopharmacology Comments
The role of PIN1 in modulating cytokine expression by activated T cells and eosinophils suggests that targeting this enzyme may offer potential for the development of therapeutics for immunologic diseases such as asthma and organ rejection [4,10-11,16].
Physiological Functions Click here for help
Converts P-tau from a cis conformation to a trans conformation. Cis P-tau has been detected in toxic tau tangles present in samples from patients with vascular dementia. Pin1 prevents neurodegeneration by limiting cis P-tau.

Physiological Consequences of Altering Gene Expression Click here for help
Brain-specific Pin1 overexpression rescues vascular contributions to cognitive impairment and dementia (VCID)-like neurodegeneration and cognitive impairment in a mouse model; likely by reducing cis P-tau levels.
Species:  Mouse
Tissue:  Brain

General Comments
PIN1 isomerises phosphorylated serine/threonine-proline bonds, a protein modification that is involved in the regulation of a range of cellular processes, including cell cycle progression [6] and protein folding and processing [1]. It has been proposed as a drug target for cancer [15] and diseases that are associated with defective amyloid protein processing such Alzheimer's disease [2,12]. Evidence also suggests that PIN1 plays a role in the immune system, in pathways that are distinct from those regulated by other immune system PPIases (peptidylprolyl isomerase A/cyclophilin A and FKBP prolyl isomerase 1A) [4].
