ABSTRACT:

INTRODUCTION
The present invention relates to the discovery, identification, and characterization of novel human polynucleotides encoding proteins sharing sequence similarity with mammalian proteases. The invention encompasses the described polynucleotides, host cell expression systems, the encoded protein, fusion proteins, polypeptides and peptides, antibodies to the encoded proteins and peptides, and genetically engineered animals that either lack or over express the disclosed sequences, antagonists and agonists of the proteins, and other compounds that modulate the expression or activity of the proteins encoded by the disclosed polynucleotides that can be used for diagnosis, drug screening, clinical trial monitoring and the treatment of physiological disorders.
BACKGROUND OF THE INVENTION
Proteases cleave protein substrates as part of degradation, maturation, and secretory pathways within the body. Proteases have been associated with, inter alia, regulating development, modulating cellular processes, and infectious disease.
SUMMARY OF THE INVENTION
The present invention relates to the discovery, identification, and characterization of nucleotides that encode a novel human protein, and the corresponding amino acid sequence of this proteins. The novel human protein (NHP) described for the first time herein shares structural similarity with animal proteases, and particularly metalloproteinases such as ADAM-TS6, a zinc metalloproteinase (Hurskainen et al., 1999, J. Biol Chem. 274(36):25555-63). However this NHP contains additional regions (exons) that make it unique.
The novel human nucleic acid (cDNA) sequences described herein, encode a proteins/open reading frames (ORFs) of 908, 292, 468, 310, 507, 589, 141, 317, 159, 356, 438, and 757 amino acids in length (see SEQ ID NOS: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, and 24).
The invention also encompasses agonists and antagonists of the described NHP, including small molecules, large molecules, mutant NHPs, or portions thereof that compete with native NHP, peptides, and antibodies, as well as nucleotide sequences that can be used to inhibit the expression of the described NHP (e.g., antisense and ribozyme molecules, and gene or regulatory sequence replacement constructs) or to enhance the expression of the described NHP (e.g., expression constructs that place the described sequence under the control of a strong promoter system), and transgenic animals that express a NHP transgene, or “knock-outs” (which can be conditional) that do not express a functional NHP.
Further, the present invention also relates to processes for identifying compounds that modulate, i.e., act as agonists or antagonists, of NHP expression and/or NHP activity that utilize purified preparations of the described NHP and/or NHP product, or cells expressing the same. Such compounds can be used as therapeutic agents for the treatment of any of a wide variety of symptoms associated with biological disorders or imbalances.
DESCRIPTION OF THE SEQUENCE LISTING
The Sequence Listing provides the sequences of the NHP ORFs encoding the described NHP amino acid sequences. SEQ ID NO: 25 describes an ORF with flanking sequences.
