G proteins

G proteins
Семейство мембранных белков, активирующихся после взаимодействия с ГТФ: участвуют в передаче сигнала от клеточных рецепторов к «усиливающим» ферментам на внутренней поверх-ности мембран - например, к аденилатциклазе.

Г-белки — семейство мембранных белков, которые активируются после присоединения к ним гуанозинтрифосфата (ГТФ). Активированные Г-б. в свою очередь активируют ферменты-амплификаторы
