Cap analysis of gene expression sequencing is performed in breast cancer MCF-7 cells.
The method identifies 15 CAGE tag clusters close to estrogen receptor binding sites.
RAMP3, ISOC1 and GPRC5C are estrogen-regulated genes with those CAGE tag clusters.
RAMP3, ISOC1 and GPRC5C will regulate growth/migration of MCF-7 cells.
CAGE sequencing is useful for global identification of estrogen-regulated promoters.
