The alpha, beta, and gamma subunits (or beta-gamma dimers) of heterotrimeric guanine nucleotide binding (G) proteins are intracellular membrane-associated proteins activated by various receptors (e.g., beta adrenergic).

(Heterotrimeric G Protein Subunit, NCI Thesaurus)

(Heterotrimeric G Protein, NCI Thesaurus)

Upon administration, fosbretabulin is dephosphorylated to its active metabolite, combretastatin A4, which targets and binds to tubulin dimers and prevents microtubule polymerization, thereby resulting in mitotic arrest and apoptosis in endothelial cells.

(Fosbretabulin Tromethamine, NCI Thesaurus)

G beta-gamma dimers associate with the alpha subunit to comprise heterotrimeric G proteins.

Nucleotide Excision Repair (NER) mends DNA regions that contain chemical adducts, such as UV-induced thymine dimers or carcinogenic adducts, which distort the DNA helix and interfere with replication and transcription.

(Nucleotide Excision Repair, NCI Thesaurus)
