Consequences of frameshift mutations at the immunoglobulin heavy chain locus of the mouse.

RESUMO
From an IgM secreting hybridoma line we have isolated 16 spontaneous mutants that produce truncated IgM polypeptides. The size of the mu-mRNAs produced by these mutants is normal, but they express 3- to 100-fold less mu-mRNA and mutant mu-protein than the parental cell line. Nucleotide sequence analysis of cloned mu-genes and/or their mRNAs show frameshift mutations that generate in-phase chain termination codons. The extent of the reduction in mu-mRNA levels depends on the position of the nonsense codon within the gene.
