Intracellular Receptors and Direct Gene Action definitions Flashcards

Lipid-soluble hormones that can pass through cell membranes to influence gene expression directly.

Hormones that cannot penetrate cell membranes and rely on second messenger systems.

Characteristic of molecules that can dissolve in lipids, allowing them to pass through cell membranes.

Proteins inside cells that bind to hormones to form a receptor-hormone complex.

A complex formed when a hormone binds to its receptor, capable of influencing gene expression.

The part of the cell where receptor proteins may bind with hormones before entering the nucleus.

Cell organelle where the receptor-hormone complex binds to DNA to affect gene expression.

Specific areas of DNA where the receptor-hormone complex binds to influence gene expression.

The process by which information from a gene is used to synthesize RNA and proteins.

Mechanism where hormones directly influence gene expression by binding to DNA.

Pathways used by amino acid-based hormones to transmit signals inside cells.

The process of copying a segment of DNA into RNA, initiated by the receptor-hormone complex.

The creation of proteins from RNA, a process influenced by steroid hormones.

Proteins that bind to steroid hormones in the blood, aiding their transport to target cells.

Alterations in body function or structure resulting from hormone-induced protein activity.
