ACTA1
Aktin alfa skeletnih mišića je protein koji je kod ljudi kodiran genom ACTA.[5][6]
Aktin alfa 1 koji se ispoljava u skeletnim mišićima jedna je od šest različitih identificiranih izoformi aktina. Aktini su visoko konzervirani proteini, koji su uključeni u pokretljivost ćelija, strukturu i integritet. Alfa aktini su glavni sastojak kontraktilnog aparata.[7]
Ekspresija aktinskog gena skeletnih mišića
urediEkspresija alfa aktina u skeletnim mišićima inducirana je podražajima i stanjima za koja je poznato da uzrokuju formiranje mišića.[8] Takvi uslovi rezultiraju fuzijom povezanih ćelija (satelitskih ćelija) u miotube, da bi se stvorila mišićna vlakna. Sam skeletni aktin, kada se eksprimira, uzrokuje ekspresiju nekoliko drugih "miogenih gena", koji su neophodni za formiranje mišića.[9] Jedan od ključnih transkripcijski faktor€transkripcijskih faktora koji aktivira ekspresiju aktinskog gena skeletnih mišića je faktor serumskog odgovora ("SRF"), protein koji se veže na određena mjesta na promotorskoj DNK aktinskog gena.[10] SRF može donijeti brojne druge proteine promotoru ovog aktina, kao što je androgeni receptor, i na taj način doprinijeti indukciji ekspresije gena aktina androgenima (često nazivanim "anaboličkim") steroid.[11]
Interakcije
urediPokazano je da aktin, alfa 1 ima interakcije sa TMSB4X,[12][13] MIB2[14] i PRKCE.[15]
