The function of Ensembl gene identifier ENSG00000153015 (CWC27, CWC27 spliceosome associated cyclophilin) is as follows. As part of the spliceosome, plays a role in pre-mRNA splicing (PubMed:29360106). Probable inactive PPIase with no peptidyl-prolyl cis-trans isomerase activity (PubMed:20676357). As a component of the minor spliceosome, involved in the splicing of U12-type introns in pre- mRNAs (Probable). {ECO:0000269|PubMed:20676357, ECO:0000269|PubMed:29360106, ECO:0000305|PubMed:33509932}.
