Гамартин, также известный как туберозный склероз 1 — белок, кодируемый у человека геномTSC1[1].
Функция
Этот периферийный мембранный белок известен как супрессор опухоли. Он образует комплекс с TSC2, который регулирует сигнализацию mTORC1 и может быть также вовлечен в везикулярный транспорт и стыковку.
