| description | Ovalbumin (OV) is present at high levels in pancreatic beta cells and in kidney proximal tubule cells and at very low levels in testes of transgenic mice. No OV has been detected immunohistologically in any of multiple other tissues examined. Mice expressing both this transgene and Tg(Tcra,Tcrb)1100Mjb (OT-1), which encodes an OV-specific T cell receptor expressed on CD8+ T lymphocytes, exhibit thymic deletion of OT-1 T cells, indicating presence of OV at very low levels in the thymus. Western blot analysis reproducibly measured the pancreatic islet OV content as 2.2 ng/ug of protein. |
| molecularNote | The transgene encodes a fusion protein comprising the carboxy-terminal 118 amino acids of the human transferrin receptor, which include the cytoplasmic tail, membrane-targeting signal and anchor domain of the protein, joined to amino acids 139-385 of mature ovalbumin. Its expression is directed by the rat insulin 2 promoter. |
