Preparation and Storage

Background: AG-2/AGR2

AG-2 (Anterior gradient protein 2; also AGR2, GOB4 and HPC8) is an 18‑21 kDa member of the PDI family of enzymes. It is expressed in secretory cell types, such as prostate epithelium, small intestine goblet, Paneth and enteroendocrine cells, and multiple carcinoma cell types. Although AG-2 possesses a signal sequence, it appears to be rarely secreted, instead being found in the ER due the presence of a KTEL ER retention signal at its C-terminus. AG-2 forms transient disulfide linkages with molecules destined for secretion, possibly aiding protein folding. Mature human AG-2 is 155 amino acids (aa) in length (aa 21‑175). Cys81 is presumed to participate in intermolecular bond formation. There is one potential alternative start site 20 aa upstream of the standard start site. Over aa 21‑175, human AG-2 shares 94% aa identity with mouse AG-2.
