摘要:
The anti-19P2 ligand monoclonal antibodies of the invention (in particular P2L-1Ca) have very high binding ability and can neutralize the arachidonic acid metabolite releasing activity of the 19P2 ligand. Therefore, they can be used, among others, as diagnostic, prophylactic and/or therapeutic agents for various diseases caused by some or other abnormality in the pituitary function modulating activity (e.g. prolactin secretion promoting activity), central nervous system modulating activity and pancreatic function modulating activity, among others, supposedly possessed by the 19P2 ligand.The immunoassay method using the monoclonal antibodies of the invention by the sandwich technique (in particular the sandwich technique using the monoclonal antibody and an antibody recognizing an intermediate portion of the 19P2 ligand) can assay the 19P2 ligand or a derivative thereof specifically and with high sensitivity. This assay method can be used in elucidating the physiological functions of the 19P2 ligand or a derivative thereof.
摘要:
The present invention provides a method for screening a compound or its salt that alters the binding property between MCH or its salt and SLC-1 or its salt, characterized by using MCH or its derivative or a salt thereof and SLC-1 or its salt is useful for screening an SLC-1 agonist which can be used not only as an appetite (eating) promoting agent but also as a prophylactic/therapeutic agent for weak pains, atonic bleeding, before and after expulsion, subinvolution of uterus, cesarean section, induced abortion, galactostasis, and the like, and an SLC-1 antagonist which can be used not only as an antiobestic agents (drug), an appetite (eating) modulator, and the like, but also as a prophylactic/therapeutic agent for hyperstimulation, ankylosing uterine contractions, fetal distress, uterine rupture, cervical laceration, preterm delivery, Prader-Wili syndrome and the like.
摘要:
The present invention relates to the ligand polypeptide for the human pituitary- and mouse pancreas-derived G protein-coupled receptor proteins. The ligand polypeptide or the DNA which codes for the ligand polypeptide can be used for (1) development of medicines such as pituitary function modulators, central nervious system function modulators, and pancreatic function modulators, and (2) development of receptor binding assay systems using the expression of recombinant receptor proteins and screening of pharmaceutical candidate compounds. In particular, by the receptor binding assay systems utilizing the expression of recombinant G protein-coupled receptor proteins in accordance with the invention, agonists and antagonists of G protein-coupled receptors which are specific to human and other warm-blooded animals can be screened and the agonists or antagonists obtained can be used as therapeutic and prophylactic agents for various diseases.

摘要:
This invention discloses a PACAP receptor protein or a salt thereof, a DNA comprising a DNA fragment coding for the protein, a method for preparing the protein, antibody against the protein, and use of the protein, DNA, and antibodies. A PACAP receptor protein was purified from the bovine cerebrum. DNAs coding for PACAP receptor proteins were isolated from bovine, rat and human cDNA libraries, and their nucleotide sequences were determined. Further, amino acid sequences deduced from the nucleotide sequences were determined. The PACAP receptor proteins and the DNAs coding for the proteins of the present invention can be used for (1) acquisition of antibodies and antisera, (2) construction of expression systems of recombinant receptor proteins, (3) development of receptor binding assay systems using said expression systems and screening of potential compounds for drugs, (4) execution of drug design based on the comparison of ligands and receptors which are structurally similar to each other, (5) preparation of probes and PCR primers in gene diagnosis, and the like.
