Peptidylprolyl isomerase D (cyclophilin D), also known as PPID, is an

Structure

Like other cyclophilins, PPID forms a

Function

The protein encoded by this gene is a member of the peptidyl-prolyl cis-trans isomerase (

Clinical Significance

As a cyclophilin, PPID binds the immunosuppressive drug CsA to form a CsA-cyclophilin complex, which then targets calcineurin to inhibit the signaling pathway for T-cell activation.

In cardiac myogenic cells, cyclophilins have been observed to be activated by heat shock and hypoxia-reoxygenation as well as complex with heat shock proteins. Thus, cyclophilins may function in cardioprotection during

ischemia-reperfusion injury
.

Currently, cyclophilin expression is highly correlated with cancer pathogenesis, but the specific mechanisms remain to be elucidated.[7] Studies have shown that PPID protects human keratinocytes from UVA-induced apoptosis, so medication and therapies that inhibit PPID, such as CsA, may inadvertently aid skin cancer development. Conversely, treatments promoting PPID activity may improve patient outcomes when paired with UVA therapies against cancer.[10]
