اکتینین آلفا ۲ (انگلیسی: Actinin alpha 2) یک پروتئین است که در انسان توسط ژن «ACTN2» کُدگذاری می‌شود.^[۴] این ژن نوع خاصی از آلفا اکتینین را کدگذاری می‌کند که ماهیچه‌های اسکلتی و قلبی بیان می‌گردد و ریزرشته‌های اکتین و تاینین را به سارکومر متصل می‌کند.

اهمیت بالینی

جهش در ژن «ACTN2» با بروز «کاردیومیوپاتی هیپرتروفیک» ^[۵] و «کاردیومیوپاتی اتساعی» و «فیبروالاستوز اندوکاردیال»^[۶] در ارتباط است.
