Abstract

Многие белки в организме млекопитающих существует в виде нескольких изоформ. Они кодируются разными генами или являются продуктами альтернативного сплайсинга одного и того же гена. Несмотря на быстрый инструментальный прогресс в идентификации изоформ, причины их существования и специфические функции в большинстве случаев остаются точно неизвестными. В последнее время в основном внимание исследователей сосредоточено на сплайсированных изоформах, в то время как разногенные белковые изоформы могут выполнять существенную роль в разных клеточных процессах. В обзоре приводятся примеры разных потенциальных функций изоформ одного и того же белка, кодируемых разными генами. Молекулярные основы существования такой функциональной разницы высокогомологичных белковых изоформ обсуждаются на примере последних достижений в изучении изоформ фактора элонгации трансляции 1A (eEF1A).
Keywords: белковые изоформы, эукариотическая трансляция, eEF1A
