ABSTRACT:

1. INTRODUCTION
The present invention relates to the discovery, identification, and characterization of novel human polynucleotides encoding proteins that share sequence similarity with animal kinases. The invention encompasses the described polynucleotides, host cell expression systems, the encoded proteins, fusion proteins, polypeptides and peptides, antibodies to the encoded proteins and peptides, and genetically engineered animals that either lack or over express the disclosed genes, antagonists and agonists of the proteins, and other compounds that modulate the expression or activity of the proteins encoded by the disclosed genes that can be used for diagnosis, drug screening, clinical trial monitoring and the treatment of physiological disorders.
2. BACKGROUND OF THE INVENTION
Kinases mediate phosphorylation of a wide variety of proteins and compounds in the cell. Along with phosphatases, kinases are involved in a wide range of regulatory pathways. Given the physiological importance of kinases, they have been subject to intense scrutiny and are proven drug targets.
3. SUMMARY OF THE INVENTION
The present invention relates to the discovery, identification, and characterization of nucleotides that encode novel human proteins, and the corresponding amino acid sequences of these proteins. The novel human proteins (NHPs) described for the first time herein share structural similarity with animal kinases, and more particularly serine/threonine protein kinases. As such, the novel sequences represent a new family of proteins having homologues and orthologs across a range of phyla and species.
The novel human nucleic acid sequences described herein, encode alternative proteins/open reading frames (ORFs) of 187, 356, 324, 198, 347, and 315 amino acids in length (see SEQ ID NOS: 2, 4, 6, 8, 10, and 12).
The invention also encompasses agonists and antagonists of the described NHPs, 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 NHPs (e.g., antisense and ribozyme molecules, and gene or regulatory sequence replacement constructs) or to enhance the expression of the described NHP sequences (e.g., expression constructs that place the described gene under the control of a strong promoter system). The present invention also includes both transgenic animals that express a NHP transgene, and NHP “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 product activity that utilize purified preparations of the described NHPs 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.
