This invention relates to gene polypeptides and polynucleotides that encode proteins of the Nogo-66 receptor (NgR) family and are therefore called NgR homologue 2 (NgRH2). The invention further relates to their use in identifying compounds that may be agonists or antagonists that are potentially useful in regeneration and protection of the nervous system, and to production of NgRH2 polypeptides, derivatives, and antibodies.
