Generic protein structure example

AT-rich interactive domain-containing protein 1B is a protein that in humans is encoded by the ARID1B gene.[1] ARID1B is a component of the human SWI/SNF chromatin remodeling complex.

Clinical significance

Germline mutations in ARID1B are associated with Coffin–Siris syndrome.[2][3] Somatic mutations in ARID1B are associated with several cancer subtypes, suggesting that it is a tumor suppressor gene.[4][5][6][7]

Interactions

ARID1B has been shown to interact with SMARCA4[8][9] and SMARCA2.[9]
