Estrogen receptor 1 (ESR1) is a major ligand-activated transcription factor, member of the family nuclear receptors [1]. ESR1 acts via two main pathways: a ligand-dependent and ligand-independent manner [2]. Activated by a ligand, ESR1 ...

In addition to the conventional hormone-dependent regulation of activity of Estrogen receptor alpha and beta (ESR1(nuclear) and ESR2 respectively), there is a cross-talk between signal transduction pathways and estrogen receptors [1]. Epidermal growth factor (EGF), ...

Androgen and Estrogen receptors (Androgen receptor and ESR1 (nuclear)) function as steroid-hormone activated transcription factors. Upon binding the hormone ligand, receptors dissociate from accessory proteins, translocate into the nucleus, dimerize, and then stimulate transcription ...

Sp1 transcription factor (SP1) is a transcription factor involved in gene expression in the early development of an organism. It belongs to the Sp/KLF family of transcription factors. The SP1 transcription factor contains a zinc finger protein motif, by which it binds directly to DNA ...
