Localization of the murine activating transcription factor 4 gene to mouse chromosome 15.
Restriction fragment length variant analysis employing a mouse cDNA probe was used to localize the gene encoding murine activating transcription factor 4 (ATF-4) to mouse chromosome 15 in close proximity to Sis (the cellular homolog of the simian sarcoma virus oncoprotein). Previous studies suggest that conserved linkage relationships exist between this region of mouse chromosome 15 and human chromosome 22q. The chromosomal locations of genes encoding most members of the ATF and cyclic AMP response element binding protein (CREB) subfamily of b-zip proteins have not been determined. This study demonstrates that the location of the gene for murine ATF-4 is not linked to the genes for JUN family members, CREB1 and CREB2. Further mapping of individual ATF/CREB subfamily members in the mouse will provide insight into the evolution of this multigene family.
