| 1 | An active-site mutation (Gly633-->Arg) of dipeptidyl peptidase IV causes its retention and rapid degradation in the endoplasmic reticulum. | Arginine | dipeptidylpeptidase 4 | Rattus norvegicus |
| 2 | Cloning and sequencing of DPPIV cDNAs revealed a G to A transition at nucleotide 1897 in the cDNA sequence of 344/CRJ, which leads to substitution of Gly633-->Arg in the active-site sequence Gly629-Trp-Ser-Tyr-Gly633 determined for the wild-type DPPIV [Ogata, S., Misumi, Y., Takami, N., Oda, K., & Ikehara, Y. | Arginine | dipeptidylpeptidase 4 | Rattus norvegicus |

| 7 | Cloning and sequencing of DPPIV cDNAs revealed a G to A transition at nucleotide 1897 in the cDNA sequence of 344/CRJ, which leads to substitution of Gly633-->Arg in the active-site sequence Gly629-Trp-Ser-Tyr-Gly633 determined for the wild-type DPPIV [Ogata, S., Misumi, Y., Takami, N., Oda, K., & Ikehara, Y. | Tyrosine | dipeptidylpeptidase 4 | Rattus norvegicus |
| 8 | Pulse-chase experiments with hepatocytes showed that the wild-type DPPIV was initially synthesized as a 103-kDa form with high-mannose-type oligosaccharides, which was processed to a mature form of 109 kDa with the complex type during intracellular transport. | mannose-type oligosaccharides | dipeptidylpeptidase 4 | Rattus norvegicus |
| 9 | Site-directed mutagenesis of the wild-type and mutant cDNAs and their transfection/expression in COS-1 cells confirmed that the single substitution of Gly633-->Arg is sufficient to cause the rapid intracellular degradation of DPPIV. | Arginine | dipeptidylpeptidase 4 | Rattus norvegicus |
