MAPK7 («митоген-активируемая белковая киназа 7»; англ. mitogen-activated protein kinase 7; ERK5 ) — цитозольная серин/треониновая протеинкиназа , семейства MAPK группы ERK , продукт гена MAPK7 [ 5] [ 6] .
MAPK7 состоит из 816 аминокислот , молекулярная масса 88,4 кДа. Описано 4 изоформы белка, предполагается существование ещё 5 изоформ.
MAPK7 , или ERK5 , — фермент семейства MAPK из группы киназ, регулируемых внеклеточными сигналами (ERK ). Киназа отвечает на разнообразные внешние сигналы и вовлечёна во множество клеточных процессов, таких как пролиферация , клеточная дифференцировка , регуляция клеточного цикла . Активация MAPK7 требует её фосфорилирования киназой MAP2K5 /MEK5 . После активации MAPK7 транслоцируется в клеточное ядро , где активирует факторы транскрипции . Известны 4 изоформы белка[ 7] .
MAPK7 играет критическую роль в развитии сердечно-сосудистой системы [ 8] и функционировании эндотелиальных клеток[ 9] [ 10] .
