Identification and Isolation of the Receptor for Pigment Epithelium-
Derived Factor (PEDF)

    Description of Technology: This application describes and claims 
compositions and methods related to PEDF-R, a receptor for pigment 
epithelium-derived factor (PEDF). PEDF (aka serpin f1 gene product) is 
a protein, belonging to the serpin superfamily with neurotrophic, 
gliastatic, neuronotrophic, antiangiogenic, and antitumorigenic 
properties. However, PEDF lacks the characteristic ability of serpins 
to inhibit serine protease activity. In particular, the compositions 
and methods described and claimed in this application are related to 
the isolation, cloning, expression and characterization of a receptor 
for PEDF, PEDF-R. The PEDF-R gene (also known as TTS-2.2, iPLA-zeta, 
ATGL, desnutrin, or PNPLA2) is located on chromosome 11. The sequence 
of the PEDF-R polypeptide is composed of 504 amino acids, and shares 
homology with other genes such as for adiponutrin and GS2, contains a 
patatin-like phospholipase A2 domain and up to four transmembrane 
regions. PEDF-R exhibits a potent phospholipase A2 activity, binds to 
PEDF ligands with high affinity, and it localizes to plasma membranes. 
An extracellular loop region is available for the interactions with 
extracellular PEDF ligand, which stimulate the phospholipase activity 
of PEDF-R. The identification of this novel PEDF-R gene in the retina 
for a phospholipase-linked membrane protein with high affinity for 
PEDF, suggests a molecular pathway by which ligand/receptor interaction 
on the cell surface could generate a cellular signal.
    Applications:
    1. Basic research to further elucidate the role of PEDF and its 
receptor in signal transduction pathways.
    2. Development of drug screening assays to identify agonists and 
antagonists of PEDF activity.
    3. Development of new biological molecules to regulate PEDF 
signaling such as monoclonal antibodies and chimeric IgG-receptor 
constructs.
    Development Stage: Information on research being conducted in Dr. 
Becerra's laboratory can be found on the Internet at http://www.nei.nih.gov/intramural/protein_struct_func.asp. The ability of 
the receptor or receptor-targeted molecules and biologics to be used as 
therapeutics remains the subject of early research and development 
efforts.

Genes Expressed in Prostate Cancer and Methods of Use

    Description of Technology: This invention is a novel gene, called 
New Gene Expressed in Prostate (NGEP). This gene appears to be 
expressed only in human prostate and prostate cancer. This gene has two 
known splice variants of significantly different size. The shorter 
splice variant encodes a cytoplasmic protein, while the longer splice 
variant encodes a plasma membrane protein, which has been detected on 
the plasma membrane of human cancer cells.
    This patent application contains claims to the polypeptide, NGEP, 
nucleotides encoding NGEP, antibodies that bind NGEP polypeptides, and 
methods of using these polypeptides, polynucleotides, and antibodies.
    The presence of the protein on the cell surface and the selective 
expression in prostate and prostate cancer make this a potential target 
for prostate cancer diagnostics and therapeutics. Potential 
therapeutics could be gene-based, vaccines, antibodies, or 
immunoconjugates.
