Funkcija

uredi

ARID1A je član porodice SWI/SNF, čiji članovi imaju aktivnosti helikaza i ATPaza i smatra se da regulišu transkripciju određenih gena mijenjajući hromatinsku strukturu oko tih gena. Kodirani protein je dio velikog ATP-ovisnog kompleksa za remodeliranje hromatina SWI/SNF, koji je potreban za transkripcijsku aktivaciju gena koji su normalno potisnuti hromatinom. Ima najmanje dva konzervirana domena koji bi mogli biti važne za njegovu funkciju. Prvo, ima ARID domen, koji je DNK-vezujući domen koji može specifično vezati AT-bogatu DNK sekvencu za koju se zna da je prepoznata putem SWI/SNF kompleksa na beta-globinskom lokusu. Drugo, C-terminal proteina može stimulirati glukokortikoidni receptorski zavisnu aktivaciju transkripcije. Smatra se da protein kodiran ovim genom daje specifičnost kompleksu SWI/SNF i može regrutirati kompleks do svojih ciljeva kroz interakcije protein-DNK ili protein-protein. Za ovaj gen su pronađene dvije varijante transkripta koje kodiraju različite izoforme.[7]

Klinički značaj

uredi

Ovaj gen je obično mutiran u karcinomima želuca,[9] ćelijama raka jajnika,[10] i raka gušterače.[11] U raku dojke udaljene metastaze dobijaju inaktivacijske mutacije u ARID1A koje se ne vide u primarnom tumoru, a smanjena ekspresija ARID1A daje rezistenciju na različite lijekove kao što su trastuzumab i mTOR-inhibitori. Ovi nalazi daju obrazloženje zašto tumori akumuliraju mutacije ARID1A-e.[12][13]

Istraživanje

uredi

Čini se da nedostatak ovog gena/proteina štiti pacove od nekih vrsta oštećenja jetre.[14]

Interakcije

uredi

Pokazalo se da ARID1A ima interakcije sa SMARCB1[15][16] i SMARCA4.[16][17]
