The present invention relates to identification of a receptor for a satiety factor, which is involved in body weight homeostasis. Mutations in this receptor are associated with obese phenotypes. In particular the present , invention relates to identification and characterization of the receptor for leptin, including a naturally occurring soluble form of the receptor that is expected to modulate leptin activity, in particular to agonize leptin activity. The invention further relates to the nucleic acids encoding the receptor, and to methods for using the receptor e.g. to identify leptin , analogs, therapeutically such as in gene therapy or in soluble form as an agonist or antagonist …

Why it's free to use
- Filed January 16, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 16, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
