A biological target is anything within a living organism to which some other entity (like an endogenous ligand or a drug) is directed and/or binds, resulting in a change in its behavior or function.
Endogenous substances and processes are those that originate from within an organism, tissue, or cell.
Membrane progesterone receptors (mPRs) are a group of cell surface receptors and membrane steroid receptors belonging to the progestin and adipoQ receptor (PAQR) family which bind the endogenous progestogen and neurosteroid progesterone, as well as the neurosteroid allopregnanolone.
Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species.
The progesterone receptor (PR), also known as NR3C3 or nuclear receptor subfamily 3, group C, member 3, is a protein found inside cells.
The progesterone receptor B (PR-B) is one of three known isoforms of the progesterone receptor (PR), the main biological target of the endogenous progestogen sex hormone progesterone.
The progesterone receptor C (PR-C) is one of three known isoforms of the progesterone receptor (PR), the main biological target of the endogenous progestogen sex hormone progesterone.
Progestogens, also sometimes spelled progestagens or gestagens, are a class of steroid hormones that bind to and activate the progesterone receptor (PR).
A protein isoform, or "protein variant" is a member of a set of highly similar proteins that originate from a single gene or gene family and are the result of genetic differences.
Sex steroids, also known as gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate androgen or estrogen receptors.
