SR cyclophilin (SRcyp) is also known as peptidyl-prolyl cis-trans isomerase G. Cyclophilins are peptidyl-prolyl isomerases (PPIases) that accelerate the folding of proteins by catalyzing the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. The function of cyclophilins is poorly understood, but their function has been linked to multiple cellular processes such as protein folding, trafficking, and chaperone activity. SRcyp is a member of the Moca family of nuclear cyclophilins and is phosphorylated in a cell cycle dependent manner. There is evidence that SRcyp may be involved in the regulation of gene expression and mRNA splicing. Alternative names for SRcyp include PPIase G, rotamase G, cyclophilin G, clk-associating RS-cyclophilin, CARS-cyclophilin, SR-cyp, CASP10, and PPIG.
