Protein

Peptidyl-prolyl cis-trans isomerase-like 2

Gene

PPIL2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

May catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides thereby assisting the folding of proteins (By similarity). May also function as a chaperone, playing a role in transport to the cell membrane of BSG for instance (PubMed:15946952). May also have a protein ubiquitin ligase activity acting as an E3 ubiquitin protein ligase or as an ubiquitin-ubiquitin ligase promoting elongation of ubiquitin chains on substrates. By mediating 'Lys-48'-linked polyubiquitination of proteins could target them for proteasomal degradation (PubMed:11435423).By similarity2 Publications1 Publication

Expressioni

Tissue specificityi

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.2 Publications
