Antibodies are purified by peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nPPIG belongs to a highly conserved class of cyclophilins that function as peptidyl-prolyl-isomerases (PPIases) to catalyze the conversion of cis-proline to trans-proline in a polypeptide chain (1-4). PPIG contains an amino-terminal cyclophilin domain followed by Nopp140 repeats that are involved in its function as a nuclear chaperone (5). The carboxy-terminal of PPIG contains a SR (arginine-serine dipeptide repeat) domain (3,4) that is involved in pre-mRNA splicing and processing (6). PPIG interacts with the carboxy-terminal domain of RNA polymerase II as well as several other SR family splicing factors. These interactions lead to changes in localization and conformation and suggest a regulatory role in transcription and pre-mRNA splicing in the elongating RNA polymerase complex (7,8). PPIG is found in the nuclear matrix and nuclear speckles and is involved in the regulation of gene expression. PPIG shows a predominantly diffuse cytoplasmic distribution at the onset of mitosis, and in late telophase the isomerase is recruited to the newly formed nuclei (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCARS-cyclophilin; CARS-Cyp; CASP10; Clk-associating RS-cyclophilin; Cyclophilin G; CYP; MGC133241; Peptidyl-prolyl cis-trans isomerase G; Peptidyl-prolyl isomerase G; peptidyl-prolyl isomerase G (cyclophilin G); peptidylprolyl isomerase G; peptidylprolyl isomerase G (cyclophilin G); PPIase G; PPIG; Rotamase G; SCAF10; SR-cyclophilin; SR-cyp; SR-related CTD-associated factor 10; SRcyp\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R\nSENSITIVITY: Endogenous\nMW (kDa): 110\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799459516585,"sku":"3803S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3803s","provider":"Iright","version":"1.0","type":"link"}
