Protein Structure

UniProt Annotation

Function

PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.

Subcellular Localization

Nucleus.

Disease Associations

Tissue Specificity

Highest expression in thymus, pancreas and testis. Also detected in heart, placenta, lung, liver, skeletal muscle, kidney, spleen, prostate, ovary, small intestine and colon. Poorly detected in brain and leukocytes. Strong protein expression in lymph node (cortical, paracortical and medullar regions), thyroid (follicular epithelial cells), testis (developing spermatozoa), stomach (cells lining the gastric pit), pancreas, kidney (proximal and distal-tubule cells and collecting duct cells but not in glomeruli), endometrium and colon (goblet cells). Moderate protein expression in spleen, prostate (epithelium and squamous cell carcinomas), placenta and adrenal gland. Weak protein expression in liver, heart, breast, ovary, and lung. No protein expression in brain and bladder. High protein expression in most lymphomas and melanomas.
