Oligonucleotide probes were synthesized according to the published cDNA sequence of human pancreatic secretory trypsin inhibitor (PSTI) and used for the screening of a cosmid library of human genomic DNA. One positive clone was isolated, and a subclone obtained after cleavage with a restriction endonucleae (BamHI) was sequenced. The subcloned fragment contained two exons separated by one intron and parts of the two other introns flanking the exons. The exons are encoding five amino acids of the signal peptide and the subsequent 42 N-terminal amino acids of the human PSTI. The available data allow the conclusion that the arrangement of exons and introns in the human PSTI gene is completely identical to that of the chicken ovomucoid and chicken ovoinhibitor genes.

UI	MeSH Term	Description	Entries
D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D014359	Trypsin Inhibitor, Kazal Pancreatic	A secreted KAZAL MOTIF-containing serine peptidase inhibitor that inhibits TRYPSIN. It is a protein composed of 56 amino acid residues and is different in amino acid composition and physiological activity from the Kunitz bovine pancreatic trypsin inhibitor (APROTININ). It protects against the trypsin-mediated premature activation of ENZYME PRECURSORS in the PANCREAS. Mutations in the SPINK1 gene are associated with CHRONIC PANCREATITIS.
