Rabbit anti estrogen receptor alpha (pSer106) antibody
recognizes estrogen receptor alpha, also known as ER-alpha, when phosphorylated at serine 106. Estrogen receptor alpha is a member of the nuclear receptor superfamily and also functions as a ligand-regulated transcription factor. Estrogen receptor alpha consists of several domains including the transcription activation function-1 domain (AF-1), the DNA-binding domain, the hinge domain and the ligand-binding domain (AF-2). Estrogen receptor alpha is phosphorylated at serine 106 by MAPKs, Cdk2 and GSK3 (Thomas et al. 2008
, Rogatsky et al. 1999
, Medunjanin et al. 2005
). Phosphorylation at serine 106 contributes to agonist independent activation of estrogen receptor alpha.
