Fourteen different major urinary protein (MUP) genomic clones from BALB/c mice were isolated. By restriction site mapping, six of these form two sets of three overlapping clones. By the criterion of cross-hybridization, the 10 different genes fall into two groups of four (Group 1) and three (Group 2) genes, while three genes fall into neither group. Southern blot analysis of genomic DNA with Group 1 and Group 2 plasmid subclones shows that the haploid mouse (BALB/c) genome contains approximately 15 Group 1 genes, 12 Group 2 genes and at least seven MUP genes that belong to neither group. An analysis of mouse-Chinese hamster hybrid cell lines shows that most, if not all, Group 1 and Group 2 genes are located on mouse chromosome 4.
