Examples of claims to DNA sequences include the following:
1. An isolated nucleic acid molecule having a sequence identity of at least 90% with SEQ ID NO: 1 and which encodes a melanocortin receptor.
2. An isolated nucleic acid molecule which codes for a polypeptide of SEQ ID NO: 2. Claim 1 above covers not only a DNA or RNA sequence of SEQ ID NO: 1, but also variants of that sequence which encode the specified receptor. (It is necessary to include a functional definition of the nucleic acid molecule (e.g. “which encodes a melanocortin receptor”) in order to exclude molecules which are non-functional.)
Polypeptide and peptide sequences
Examples of claims to polypeptide and peptide sequences include the following:
3. A purified polypeptide comprising an amino acid sequence having at least 95% sequence identity with SEQ ID NO: 2 and which binds FSH with a Ki of less than 10 nM.
4. A peptide of formula X1-X2-A-G-C-X3-L-V-F-X4, wherein X1 is acetyl or is absent; X2 is L or I; X3 is F or W; and X4 is amide or is absent.
