Beta-aktin (skraćenica ljudskog gena i proteina ACTB/ACTB) jedna je od šest različitih aktinskih izoformi koje su identifikovane kod ljudi. Ovo je jedan od dva nemišićna citoskeletna aktina. Aktini su visoko konzervirani proteini^[5]^[6] koji su uključeni u pokretljivost strukturu i integritet ćelija. Alfa aktini su glavni sastojak kontraktilnog aparata.^[7]

Interakcije uredi

Dokazano je da beta-aktin imaju interakcije sa SPTBN2.^[8]^[9] Pored toga, utvrđeno je da RNK-vezujući protein Sam68 komunicira s iRNK koja kodira β-aktin, koji regulira sinapsnu tvorbu dendritskih grana sa svojim citoskeletnim komponentama.

Pokazano je da beta-aktin aktivira eNOS, povećavajući time proizvodnju NO. Pokazalo se da ostatak od osam aminokiselina (326-333) u aktinu posreduje u interakciji između aktina i eNOS.^[10]

Klinički značaj uredi

Povratne mutacije u ovom genu povezane su sa slučajevima difuznim limfomom velikih ćelija.^[11]

Primjena uredi

Beta aktin se često koristi u Western blotingu kao kontrola opterećenja, za normalizaciju ukupnih količina proteina i provjeru eventualne razgradnje proteina u uzorcima. Njegov transkript se također koristi se kao standard za održavanje stanja u qPCR. Njegova molekulska težina je približno 42 kDa.
