DescriptionAnti-GREB1 Antibody, clone GREB1Ab
Alternate Names
  • growth regulation by estrogen in breast cancer 1
  • Gene regulated in breast cancer 1 protein
  • protein GREB1
  • gene regulated by estrogen in breast cancer protein
Background InformationGREB1, also known as gene regulated in breast cancer protein 1 is shown to be involved in the proliferation of breast cancer cells, controlled by estrogen. GREB1 has the potential to be a clinical marker for response to endocrine therapy and a therapeutic target. GREB1 also may be the regulator for prostate cancer.
Product Information
  • MCF-7 cell lysate
PresentationPurified mouse monoclonal IgG1κ in buffer containing 0.1 M Tris-Glycine (pH 7.4), 150 mM NaCl with 0.05% sodium azide.
Quality LevelMQ100
ApplicationThis Anti-GREB1 Antibody, clone GREB1Ab is validated for use in WB, IH, IC for the detection of GREB1.
Key Applications
  • Western Blotting
  • Immunohistochemistry
  • Immunocytochemistry
Application NotesImmunohistochemistry Analysis: 1:600 dilution from a previous lot detected GREB1 in prostate tissue.

Immunocytochemistry Analysis: A previous lot was used by an independent laboratory in IP. (Hnatyszyn, H., et al. 2009). Breast Cancer Res Treat
DOI 10.1007/s10549-009-0584-x.)

Antibody TypeMonoclonal Antibody
Entrez Gene Number
Entrez Gene SummaryThis gene is an estrogen-responsive gene that is an early response gene in the 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. [provided by RefSeq].
Gene Symbol
  • GREB1
Purification MethodProtein G
UniProt Number
UniProt SummaryFUNCTION: Unknown. Primary target for estrogen receptor regulation. Acts as a regulator of hormone-dependent cancer growth in breast and prostate cancers.

SUBCELLULAR LOCATION: Membrane; Single-pass membrane protein (Potential).

TISSUE SPECIFICTY: Expressed in proliferating prostatic tissue and prostate cancer.

INDUCTION: Estrogen-responsive; regulated by estrogen receptors. Regulated by androgens. The regulatory region of the gene contains 3 estrogen-responsive elements.

SEQUENCE SIMILARITIES: Belongs to the GREB1 family.

SEQUENCE CAUTION: The sequence BAA25501.2 differs from that shown. Reason: Erroneous initiation.
Molecular Weight~ 216 kDa observed. Uncharacterized bands may be observed in some lysates.
