Abstract: The present invention relates to LLG polypeptides, which are polypeptides of the triacylglycerol lipase family, and fragments thereof, antibodies against such polypeptides, nucleic acids encoding such polypeptides, and antisense nucleic acids derived from such nucleic acids. The invention relates also to therapeutic compositions and methods comprising the above. In addition, the invention relates to the preparation of LLG polypeptides using recombinant technology and to the use of LLG polypeptides to screen for agonists and antagonists thereof.

Abstract: The present invention relates to compositions for use in raising or lowering the level of LIPG polypeptide in a patient. Embodiments of the composition include compositions comprising: an anti-sense nucleic acid; a neutralizing antibody; an intracellular binding protein; an inhibitor which inhibits the enzymatic activity of LIPG polypeptide; an inhibitor which inhibits the expression of LIPG gene; a ribozyme; an LIPG polypeptide; an enhancer which increases the enzymatic activity of LIPG polypeptide; or an enhancer which increases the expression of LIPG gene. The invention relates also to methods for using the above compositions. In addition, the invention relates to a method for diagnosing a predisposition to lower cholesterol, a method for determining whether a test compound can inhibit the enzymatic reaction between LIPG polypeptide and HDL cholesterol, and methods for determining whether a test compound can enhance the enzymatic reaction between LIPG polypeptide and LDL or VLDL cholesterol.

Abstract: Hybridoma cell lines producing monoclonal antibodies specific to the human epidermal growth factor receptor are disclosed. The antibodies are capable of inhibiting the growth of human tumor cells expressing human epidermal growth factor receptors. Therapeutic uses of these monoclonal antibodies by themselves and in combination with anti-neoplastic agents are also disclosed.

Abstract: This invention provides a unique SH3 binding domain core motif of the sequence RPLPXXP and cDNA clones encoding proteins which interact with the SH3 domain of c-src, as well as the amino acid sequences which mediate this binding.Another embodiment of this invention is a method of identifying SH3-binding proteins and elucidating the sequences which mediate binding. This method may be used as an assay to select compounds which bind to this site and which inhibit or enhance the binding of the SH3 domain.
