Ppib Gene Summary [Rat]
Predicted to enable RNA polymerase binding activity; cyclosporin A binding activity; and peptidyl-prolyl cis-trans isomerase activity. Predicted to be involved in several processes, including neutrophil chemotaxis; positive regulation by host of viral genome replication; and protein peptidyl-prolyl isomerization. Located in smooth endoplasmic reticulum. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 9. Orthologous to human PPIB (peptidylprolyl isomerase B).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ppib often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
