The present invention re-, lates to novel receptor polypeptides, which, upon interaction, with certain ligands or activation, by certain compounds, modulate transcription of certain genes by, binding to cognate response elements associated with promoters, of such genes. The novel receptors of the invention modulate, transcription in the presence of retinoid compounds. The recep-, tors of the present invention differ significantly from known reti-, noid acid receptors in protein, primary sequence and in responsiveness to exposure to various, retinoids. The invention provides DNAs encoding the novel recep-, tors, expression vectors for expression of the receptors, cells, transformed with such …

Why it's free to use
- Filed January 22, 1991 and granted March 25, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 22, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 22, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
