On the genomics of immunoglobulins in the gray, short-tailed opossum Monodelphis domestica.

ABSTRACT: Annotated maps of the IGH, IGK, and IGL loci in the gray, short-tailed opossum Monodelphis domestica were generated from analyses of the available whole genome sequence for this species. Analyses of their content and organization confirmed a number of previous conclusions based on characterization of complementary DNAs encoding opossum immunoglobulin heavy and light chains and limited genomic analysis, including (a) the predominance of a single immunoglobulin heavy chain variable region (IGHV) subgroup and clan, (b) the presence of a single immunoglobulin (Ig)G subclass, (c) the apparent absence of an IgD, and (d) the general organization and V gene complexity of the IGK and IGL light chain loci. In addition, several unexpected discoveries were made including the presence of a partial V to
