MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This locus encodes an AT-rich DNA interacting domain-containing protein. The encoded protein is a component of the SWI/SNF chromatin remodeling complex and may play a role in cell-cycle activation. The protein encoded by this locus is similar to AT-rich interactive domain-containing protein 1A. These two proteins function as alternative, mutually exclusive ARID-subunits of the SWI/SNF complex. The associated complexes play opposing roles. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2016]

Protein Function and Prediction

Arid1b encodes ARID1B (alternatively, ELD/OSA1) is in a small subset of SWI/SNF complexes that function in the remodeling of chromatin (1;2). The ARID1B protein has N-terminal alanine- and glutamine-rich regions, an ARID (AT-rich interaction domain), and 2 Eld/Osa homology domains (EHD1 and EHD2) in its C-terminal half (1;2). ARID1B has several LxxLL motifs that are proposed to facilitate the interaction of ARID1B with nuclear hormone receptors (2).

Expression/Localization

RT-PCR ELISA detected variable ARID1B expression in all tissues examined (3). Highest expression was in skeletal muscle, followed by ovary, kidney, and most specific adult brain regions examined, and lowest expression was in testis (3). In situ hybridization of mouse embryonic day 16 embryos determined that ARID1B is highly expressed in select regions of the brain and in the retina (1). Western blot analysis detected ARID1B in all human tissues examined and in mouse brain (2). Immunocytochemistry determined that ARID1B is localized to the nuclei in transfected COS-7 cells (2).

Background

Mutations in ARID1B are linked to autosomal dominant mental retardation 12 [OMIM: 614562; (4-6)].
