Reduced steroid activation of elephant shark glucocorticoid and mineralocorticoid receptors after inserting four amino acids from the DNA-binding domain of lamprey corticoid receptor-1

no code implementations25 Feb 2023 Yoshinao Katsu, Jiawen Zhang, Michael E. Baker

Atlantic sea lamprey contains two corticoid receptors (CRs), CR1 and CR2, that are identical except for a four amino acid insert (Thr-Arg-Gln-Gly) in the CR1 DNA-binding domain (DBD).

Divergent Evolution of Progesterone and Mineralocorticoid Receptors in Terrestrial Vertebrates and Fish Influences Endocrine Disruption

no code implementations20 Nov 2021 Michael E. Baker

Here I discuss that due to evolution of the progesterone receptor (PR) and mineralocorticoid receptor (MR) after ray-finned fish and terrestrial vertebrates diverged from a common ancestor, each receptor evolved to respond to different steroids in ray-finned fish and terrestrial vertebrates.

Aldosterone and Dexamethasone Activate African Lungfish Mineralocorticoid Receptor: Increased Activation After Removal of the Amino-Terminal Domain

no code implementations27 Jun 2021 Yoshinao Katsu, Shin Oana, Xiaozhi Lin, Susumu Hyodo, Michael E. Baker

Aldosterone, the main physiological mineralocorticoid in humans and other terrestrial vertebrates, first appears in lungfish, which are lobe-finned fish that are forerunners of terrestrial vertebrates.

Regulation by Progestins, Corticosteroids and RU486 of Activation of Elephant Shark and Human Progesterone Receptors: An Evolutionary Perspec

no code implementations24 Jan 2021 Xiaozhi Lin, Wataru Takagi, Susumu Hyodo, Shigeho Ijiri, Yoshinao Katsu, Michael E. Baker

At 1 nM steroid, human PR is activated only by progesterone and11-deoxycorticosterone indicating increased specificity for progestins and corticosteroids during the evolution of human PR.
