Multiplicity of germline genes specifying a group of related mouse kappa chains with implications for the generation of immunoglobulin diversity. 1978

O Valbuena, and K B Marcu, and M Weigert, and R P Perry

The number of germline genes specifying the variable sequences of the Vkappa21 group of light chains was determined by saturation hybridisation analysis to be four to six. This gene multiplicity is considerably less than the total variability in the group, indicating that kappa-chain diversity is generated by somatic mutations in both framework and complementarity-determining (hypervariable) regions.

UI	MeSH Term	Description	Entries
D007135	Immunoglobulin Variable Region	That region of the immunoglobulin molecule that varies in its amino acid sequence and composition, and comprises the binding site for a specific antigen. It is located at the N-terminus of the Fab fragment of the immunoglobulin. It includes hypervariable regions (COMPLEMENTARITY DETERMINING REGIONS) and framework regions.

D007147	Immunoglobulin Light Chains	Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.

D009154	Mutation	Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.	Mutations
D009194	Myeloma Proteins	Abnormal immunoglobulins characteristic of MULTIPLE MYELOMA.	M Components,Proteins, Myeloma
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.
