Tretinoin 100-113 POU class 5 homeobox 1 Homo sapiens 0-4 1915274-1 1991 Oct3 is an embryonic octamer-binding transcription factor, whose expression is rapidly repressed by retinoic acid (RA). Tretinoin 115-117 POU class 5 homeobox 1 Homo sapiens 0-4 1915274-2 1991 In this report, we have determined the transcriptional control region of the oct3 gene and studied the mechanism of the RA-mediated repression. Tretinoin 120-122 POU class 5 homeobox 1 Homo sapiens 77-81 1915274-10 1991 We suggest that RARE1 is a critical cis element for oct3 gene expression in embryonic stem cells and for the RA-mediated repression. Tretinoin 16-18 POU class 5 homeobox 1 Homo sapiens 52-56
