Human alpha 2-macroglobulin gene is located on chromosome 12. 1985

G I Bell, and L B Rall, and R Sanchez-Pescador, and J P Merryweather, and J Scott, and R L Eddy, and T B Shows

A cDNA clone encoding amino acids 809-1451 of the protease inhibitor alpha 2-macroglobulin has been isolated from an adult human liver cDNA library. This cDNA was used to examine DNA samples prepared from a panel of human-mouse somatic cell hybrids with different numbers and combinations of human chromosomes for the presence of the human alpha 2-macroglobulin gene. The cosegregation of this gene and chromosome 12 in the cell hybrid panel indicated that the alpha 2-macroglobulin structural gene (designated A2M) is on human chromosome 12.

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.

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).

D004262 DNA Restriction Enzymes Enzymes that are part of the restriction-modification systems. They catalyze the endonucleolytic cleavage of DNA sequences which lack the species-specific methylation pattern in the host cell's DNA. Cleavage yields random or specific double-stranded fragments with terminal 5'-phosphates. The function of restriction enzymes is to destroy any foreign DNA that invades the host cell. Most have been studied in bacterial systems, but a few have been found in eukaryotic organisms. They are also used as tools for the systematic dissection and mapping of chromosomes, in the determination of base sequences of DNAs, and have made it possible to splice and recombine genes from one organism into the genome of another.
