The whole cell lysates derived from MCF-7 were immunoblotted by ESR1 (phopho S167) polyclonal antibody (Cat # PAB12621) at 1 : 500 (Lane 1). The immunoreactive band is blocked by pre-incubation of immunizing peptide (Lane 2).
Immunohistochemical staining of human breast cancer tissue stained with ESR1 (phospho S167) polyclonal antibody (Cat # PAB12621) at 1 : 200 for 10 min at RT. Staining of formalin-fixed tissue requires boiling tissue sections in 10 mM Citrate Buffer, pH 6.0 for 10 min followed by cooling at RT for 20 min.
This gene encodes an estrogen receptor, a ligand-activated transcription factor composed of several domains important for hormone binding, DNA binding, and activation of transcription. The protein localizes to the nucleus where it may form a homodimer or a heterodimer with estrogen receptor 2. Estrogen and its receptors are essential for sexual development and reproductive function, but also play a role in other tissues such as bone. Estrogen receptors are also involved in pathological processes including breast cancer, endometrial cancer, and osteoporosis. Alternative splicing results in several transcript variants, which differ in their 5' UTRs and use different promoters. [provided by RefSeq
