The present invention relates to a member of a novel gene family referred to as developmentally-regulated endothelial cell locus-1 (del-1). In particularly, the invention related to del-1 nucleotide sequences, Del-1 amino acid sequences, methods of expressing a functional gene product, and methods of using the gene and gene product. Since del-1 is expressed in endothelial cells and certain cancer cells, it may be useful as an endothelial cell and tumor marker. In addition, anti-Del-1 antibodies for immunological assessment of Del-1 protein expression as well as for inhibiting or stimulating Del-1 function are provided.

Hybrid immunoglobulin-enzyme molecules are provided which are composed of antibodies, or derivatives or fragments thereof, which specifically bind an arterial or venous thrombus that are operably linked to the enzymatically active portions of thrombolytic enzymes such as plasminogen activators. In a preferred embodiment the hybrid molecules specifically bind to fibrin and have fibrinolytic activity. The hybrid molecules of the present invention may be produced by any means, including chemical conjugation, or by means of recombinant DNA, genetic engineering and/or hybridoma technology. Methods for making and using the molecules in diagnosis and therapy are also disclosed.

Hybrid immunoglobulin-thrombolytic enzyme molecules which specifically

Methods and compositions for cell-specific expression of genes are provided. The invention utilizes the endothelin-1 promoter and promoter elements to direct expression of heterologous genes in endothelial cells. The promoters and elements are useful for directing cell-specific expression of therapies for vascular and cardiovascular diseases.
