Abstract
A novel gamma retinoic acid receptor is disclosed. The novel receptor is encoded for by cDNA carried on plasmid pGEM-hRARγ, which has been deposited with the American Type Culture Collection for patent purposes. Chimeric receptor proteins are also disclosed. The chimera contain at least one functional domain from the new gamma retinoic acid receptor.
Claims4
An isolated RARγ protein having the amino acid sequence set forth in FIG. 1 and any of the following variations of this sequence, a mutation in a DNA binding domain sequence that does not substantially effect DNA binding function or a mutation of a ligand binding domain sequence that does not substantially effect ligand binding function.
An isolated protein having the amino acid sequence of the hRARγ-encoding portion of clone pGEM-h hRARγ (ATCC Accession No. 40623) and any of the following variations of this sequence, a mutation in a DNA binding domain sequence that does not substantially effect DNA binding function or a mutation of a ligand binding domain sequence that does not substantially effect ligand binding function.
A chimeric receptor having a functional N-terminus domain, a functional DNA-binding domain, and a functional ligand-binding domain, and a ligand-binding domain,
- wherein the N-terminus domain of said chimeric receptor is obtained from the N-terminus domain of retinoic acid receptor-alpha (RARα), retinoic acid receptor-beta (RARβ), retinoic acid receptor-gamma (RARγ), glucocorticoid receptor (GR), mineralocorticoid receptor (MR), progesterone receptor (PR), estrogen receptor (ER), estrogen-related receptor-1 (ERR1), estrogen-related receptor-2 (ERR2), vitamin D3 receptor (VDR), thyroid receptor (TR), the v-erb-A receptor, or the Drosophila E75 receptor,
- wherein the DNA-binding domain of said chimeric receptor is obtained from the DNA-binding domain of RARα, RARβ, RARγ, GR, MR, PR, ER, ERR1, ERR2, VDR, TR, the v-erb-A receptor, or the Drosophila E75 receptor, and
- wherein the ligand-binding domain of said chimeric receptor is obtained from the ligand-binding domain of RARα, RARβ, RARγ, GR, MR, PR, ER, ERR1, ERR2, VDR, TR, the v-erb-A receptor, or the Drosophila E75 receptor,
- wherein at least one of the domains of said chimeric receptor comprises a contiguous portion unique to RARγ.
