Summary: Predicted to enable RNA polymerase binding activity; cyclosporin A binding activity; and peptidyl-prolyl cis-trans isomerase activity. Predicted to contribute to collagen binding activity. Predicted to be involved in several processes, including neutrophil chemotaxis; positive regulation by host of viral genome replication; and protein peptidyl-prolyl isomerization. Part of endoplasmic reticulum chaperone complex. Is expressed in several structures, including axial skeleton; cranium; inner ear; and pancreas tip epithelium. Used to study osteogenesis imperfecta type 9. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 9. Orthologous to human PPIB (peptidylprolyl isomerase B).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
