Abstract: An nNOS associated protein designated PIN-1 (Protein Inhibitor of nNOS) has been identified. It physically interacts with nNOS and inhibits its activity. Multiple lines of evidence indicate that PIN-1 is a regulator of nNOS: it is physiologically associated with nNOS, and it inhibits its catalytic activity. The extraordinary evolutionary conservation of PIN-1 and preliminary evidence that it interacts with multiple proteins, suggests that it may be a major biological regulatory protein influencing numerous physiological processes.

Abstract: An immunoassay for Sarcocystis neurona antibodies in equines is described. The immunoassay uses blocking of Sarcocystis antigens by antibodies to Sarcocystis sp. other than Sarcocystis neurona in connection with the immunoassay.

Abstract: Disclosed are purified and isolated DNA sequences encoding eukaryotic proteins possessing biological properties of inosine 5'-monophosphate dehydrogenase ("IMPDH"). Illustratively, mammalian (e.g., human) IMPDH-encoding DNA sequences are useful in transformation or transfection of host cells for the large scale recombinant production of the enzymatically active expression products and/or products (e.g., GMP) resulting from IMPDH catalyzed synthesis in cells. Vectors including IMPDH-encoding DNA sequences are useful in gene amplification procedures. Recombinant proteins and synthetic peptides provided by the invention are useful as immunological reagents and in the preparation of antibodies (including polyclonal and monoclonal antibodies) for quantitative detection of IMPDH.

Abstract: Using as a host Escherichia coli which expresses lactose operon under the control of the promoter/enhancer of tyrosine phenol lyase gene derived from Erwinia herbicola, a DNA fragment coding for tyrosine repressor (tyrR) having an amino acid sequence depicted in SEQ ID NO: 2 in Sequence Listing is obtained from the chromosome gene library of Erwinia herbicola.

Abstract: Disclosed are compositions and methods for aiding in the diagnosis of congenital muscular dystrophy associated with in-frame deletion in the laminin-2 .alpha.2 polypeptide chain in an individual. In a preferred diagnostic method embodiment, an experimental muscle tissue sample is provided from the individual and treated if necessary to render components available for antibody binding. The components of the sample are then separated on the basis of molecular weight. The separated protein components are then transferred to a solid support while maintaining the relative positions established in separation step. The transferred components are then stained with an affinity reagent which is known to bind to a C-terminal domain of the laminin-2 .alpha.2 polypeptide chain. Individual afflicted with congenital muscular dystrophy associated with in-frame deletion in the laminin-2 .alpha.2 polypeptide chain on the basis of positive staining in combination with reduced molecular weight of the laminin-2 .alpha.

Abstract: The invention provides pyrH polypeptides and polynucleotides encoding pyrH polypeptides and methods for producing such polypeptides by recombinant techniques. Also provided are methods for utilizing pyrH polypeptides to screen for antibacterial compounds.

Abstract: A purified polypeptide which provides for initial binding of sperm to oocyte investments and has an active amino acid sequence of SEQ ID NO:12 (Cys-Gln-Ser-Leu-Gln-Glu-Tyr-Leu-Ala-Glu-Gln-Asn-Gln-Arg-Gln-Leu-Glu-Ser-A sn-Lys-Ile-Pro-Glu-Val-Asp-Leu-Ala-Arg-Val-Val-Ala-Pro-Phe-Met-Ser-Asn-Ile- Pro-Leu-Leu-Leu-Tyr-Pro-Gln-Asp-Arg-Pro-Arg-Ser-Gln-Pro-Gln-Pro-Lys-Ala-Asn -Glu-Asp-Val-Cys); or SEQ ID NO:13 (Cys-Glu-Ser-Leu-Gln-Lys-His-Leu-Ala-Glu-Leu-Asn-His-Gln-Lys-Gln-Leu-Glu-S er-Asn-Lys-Ile-Pro-Glu-Leu-Asp-Met-Thr-Glu-Val-Val-Ala-Pro-Phe-Met-Ala-Asn- Ile-Pro-Leu-Leu-Leu-Tyr-Pro-Gln-Asp-Gly-Pro-Arg-Ser-Lys-Pro-Gln-Pro-Lys-Asp -Asn-Gly-Asp-Val-Cys); or the shorter but biologically active SEQ ID NO:1 and SEQ ID NO:9 (Tyr-Pro-Gln-Asp-Arg-X-Arg-Ser-Gln-Pro-Gln-Pro-Lys-Ala-Asn, where X is Thr or Pro).

Abstract: The present invention provides a 120-kDa protein gene of Ehrlichia canis, amplified by PCR using primers derived from the DNA sequences flanking the Ehrlichia chaffeensis 120-kDa protein gene. The recombinant E. canis 120-kDa protein contains 14 tandem repeat units with 36 amino acids each. The repeat units are hydrophilic and predicted to be surface-exposed. Also disclosed is that the recombinant E. canis 120-kDa protein is antigenic and reacts with sera from dogs convalescent from canine ehrlichiosis.
