title: A new allele at the Mup-1 locus controlling an electrophoretic variant of major urinary proteins in mice.
abstract: The present study showed that the presence or absence of a new component of major urinary proteins (Mups), which is found in MOA mice, an inbred strain of Mus musculus molossinus (Japanese wild mice), is controlled by a single codominant gene locus. The linkage analysis shows that the locus is on chromosome 4, where the Mup-1 locus is assigned; its alleles, Mup-1a, and Mup-1b determine two phenotypic forms of MUPs in laboratory mice (M. m. domesticus). Recombination values between the locus and other loci on chromosome 4, such as brown (b), Pgm-2, and Gpd-1 are compatible with the gene order, Mup-1-b-Pgm-2-Gpd-1, on chromosome 4. Thus, it is concluded that the locus is identical to Mup-1 and it is proposed that Mup-1c be designated as the allele that determines a third phenotypic form of MUPs in MOA mice.
