Endotoxin Level: Predicted Molecular Mass:21 kDa SDS-PAGE:20-22 kDa, reducing conditions Activity:Measured by its ability to release L-alanine from gamma -glutamyl-L-alanine, with the detection of alanine by alanine dehydrogenase.The specific activity is >40,000 pmol/min/µg, as measured under the described conditions. Formulation:Supplied as a 0.2 µm filtered solution in Tris and NaCl.See Certificate of Analysis for details. Molecule Information: gamma-Glutamylcyclotransferase/CRF21 Long Name: Cytochrome c Releasing Factor 21 Aliases: C7orf24; CRF21; GCTG; GGC; GGCT; LOC79017 Entrez Gene IDs: 79017 (Human); 110175 (Mouse); 685702 (Rat) Background: CRF21 CRF21 (Cytochrome c-releasing factor 21; also C7orf24 or LOC79017) is a 21 kDa AIG2-like family member. It is a cytosolic protein that induces the release of Cytochrome c from mitochondria, possibly initiating apoptosis. Human CRF21 is 188 amino acids (aa) in length and is a complex of beta-sheets and alpha-helices that create two terminal domains. It has been proposed that CRF21 forms homodimers. There are at least two possible splice variants of human CRF21, one showing a 70 aa substitution, while the second variant shows an 18 aa substitution for aa 97-188. Full-length human CRF21 is 82% aa identical to mouse CRF21.
