Summary
PPIL2 (peptidylprolyl isomerase like 2, HGNC:9261) is a protein-coding gene on chromosome 22q11.21, encoding RING-type E3 ubiquitin-protein ligase PPIL2 (Q13356). Has a ubiquitin-protein ligase activity acting as an E3 ubiquitin protein ligase or as an ubiquitin-ubiquitin ligase promoting elongation of ubiquitin chains on substrates. It is a common-essential gene (DepMap: required in 97.8% of cancer cell lines).
This gene is a member of the cyclophilin family of peptidylprolyl isomerases. The cyclophilins are a highly conserved ubiquitous family, members of which play an important role in protein folding, immunosuppression by cyclosporin A, and infection of HIV-1 virions. This protein interacts with the proteinase inhibitor eglin c and is localized in the nucleus. Alternatively spliced transcript variants have been found for this gene.

Function. Has a ubiquitin-protein 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. May also function as a chaperone, playing a role in transport to the cell membrane of BSG/Basigin for instance. Probable inactive PPIase with no peptidyl-prolyl cis-trans isomerase activity. As a component of the minor spliceosome, involved in the splicing of U12-type introns in pre-mRNAs.
Subunit / interactions. Component of the minor spliceosome, which splices U12-type introns. Within this complex, interacts with PRPF8/PRP8, EFTUD2/SNU114 and PLRG1. Interacts with isoform 2 of BSG. Interacts (via the PPIase cyclophilin-type domain) with CRNKL1; they may form a trimeric complex with HSP90.
Subcellular location. Nucleus.
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.
Pathway. Protein modification; protein ubiquitination.
Similarity. Belongs to the cyclophilin-type PPIase family. PPIL2 subfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 94 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
