Figure 1.

Casein, salivary, and EMP gene cluster on human 4q13. Locations of the gene products (milk, saliva, and enamel) are shown on the top. Two salivary protein gene complexes, proximal and distal, are shown. Gene symbols, locations, and transcriptional polarities are indicated at the bottom. Filled and open boxes represent the locations of functional genes and pseudogenes, respectively. The scale represents sequence contigs. The 3′ half of AMBN is not included in the human draft genome sequence (gap). The length of AMBN was inferred from the mouse gene.
