GREB1

Growth regulation by estrogen in breast cancer 1 is a is_associated_with::protein that in humans is encoded by the GREB1 is_associated_with::gene.

Function
This gene is an is_associated_with::estrogen-responsive gene that is an early response gene in the is_associated_with::estrogen receptor-regulated pathway. It is thought to play an important role in hormone-responsive tissues and cancer. Three alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
