Abstract
A 140.7-kb segment of zebrafish genomic DNA known to contain odorant receptor (OR) genes was fully sequenced to characterize more completely the organization of this gene cluster. A total of 20 OR genes were identified in this region. The most highly related genes are grouped in closest proximity to one another and in the same transcriptional orientation, indicating that a series of tandem duplications was responsible for the expansion of the OR gene family in teleost fish. Our analysis also revealed sequences that may be Involved in the transcriptional regulation of OR genes within the cluster.
