ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing protein 3A (ARID3A) and similar proteins; ARID3A, also called B-cell regulator of IgH transcription (Bright), dead ringer-like protein 1 (Dril1), or E2F-binding protein 1 (E2FBP1), is an ubiquitously expressed DNA-binding protein that has been implicated in embryonic patterning, cell lineage gene regulation, and cell cycle control, chromatin remodeling and transcriptional regulation. It was originally identified as a B cell-specific trans-activator of immunoglobulin heavy-chain (IgH) transcription, which increases immunoglobulin transcription in antigen-activated B cells and plays regulatory roles in hematopoiesis. It also functions as an E2F transcription regulator, inducing promyelocytic leukemia protein (PML) reduction and suppressing the formation of PML-nuclear bodies. It antagonizes the p16(INK4A)-Rb tumor suppressor machinery by regulating PML stability. ARID3A transcriptional activity can be modulated by SUMO (Small Ubiquitin-related Modifier) modification through the interaction with the SUMO-conjugating enzyme Ubc9. ARID3A also plays an important role in marginal zone B lymphocyte development and autoantibody production. Furthermore, ARID3A is a direct p53 target gene. It controls cell growth in a p53-dependent manner. ARID3A contains an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a SUMO-I conjugation (SUMO) motif and a multifunctional homomerization/nuclear export REKLES domain, which consists of two subdomains: a modestly conserved N-terminal REKLES alpha and a highly conserved (among ARID3 orthologous proteins) C-terminal REKLES beta.

ARID/BRIGHT DNA binding domain found in AT-rich interactive domain-containing proteins ARID1A, ARID1B and similar proteins; This subfamily contains ARID1A and its paralog ARID1B. They are mutually exclusive components of human SWItch/Sucrose NonFermentable (SWI/SNF) chromatin remodeling protein complexes, but display different functions in development and cell-cycle control. SWI/SNF complexes containing ARID1A have an antiproliferative function, whereas the one harboring ARID1B shows a pro-proliferative function. ARID1A functions as an important tumor suppressor in various tumor types. It has been implicated in cell-cycle arrest, as well as in the interactions with p53 and BRG1/BRM and with topoisomerase II alpha. ARID1B may be considered as a potential therapeutic target for ARID1A-mutant cancers. Moreover, mutations in the ARID1B gene cause Coffin-Siris syndrome, exhibiting developmental defects, and haplo-insufficiency of ARID1B is a frequent cause of intellectual disability. Mutations in the ARID1B gene also have been found in many cancers. Both ARID1A and ARID1B contain an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), which binds DNA in a non-sequence-specific manner.

ARID/BRIGHT DNA binding domain of Arabidopsis thaliana high mobility group B proteins HMGB9, HMGB10, HMGB11, HMGB15 and similar proteins; This subfamily includes a group of conserved plant DNA-binding proteins, including HMGB9 (or ARID-HMG1), HMGB10 (or ARID-HMG2), HMGB11, and HMGB15. They have been termed ARID-HMG proteins, due to containing two DNA-binding domains, an N-terminal AT-rich DNA-interacting domain (ARID, also known as BRIGHT), and a C-terminal high mobility group (HMG)-box domain. They are widely expressed in Arabidopsis and localize primarily to the nucleus. HMGB9/ARID-HMG1 binds specifically to A/T-rich DNA. HMGB15 is a transcription factor predominantly expressed in mature pollen grains and pollen tubes. It may work in the form of a homodimer, or interact with HMGB9, HMGB10 and HMGB11 to form heteromultimers in plant cells. HMGB15 is required for pollen tube growth in Arabidopsis and is involved in transcriptional regulation through the interaction with AGL66 and AGL104.

ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing proteins ARID5A, ARID5B, and similar proteins; This subfamily contains ARID5A and its paralog ARID5B. ARID5A, also called modulator recognition factor 1 (MRF-1), is an estrogen receptor alpha (ER alpha)-interacting protein that is expressed abundantly in cardiovascular tissues and suppresses ER alpha-induced transactivation. It also plays an important role in the promotion of inflammatory processes and autoimmune diseases. ARID5B, also called MRF1-like protein or modulator recognition factor 2 (MRF-2), is a DNA-binding protein that directly interacts with plant homeodomain (PHD) finger 2 (PHF2) to form a protein kinase A (PKA)-dependent PHF2-ARID5B histone H3K9Me2 demethylase complex. It also functions as a transcriptional co-regulator for the transcription factor sex determining region Y (SRY)-box protein 9 (Sox9) and promotes chondrogenesis through histone modification. Moreover, ARID5B is highly expressed in the cardiovascular system and may play essential roles in the phenotypic change of smooth muscle cells (SMCs) through its regulation of SMC differentiation. Both ARID5A and ARID5B contain an AT-rich DNA-interacting domain (ARID, also known as BRIGHT).

ARID/BRIGHT DNA binding domain of AT-rich interactive domain-containing protein 5A (ARID5A) and similar proteins; ARID5A, also called modulator recognition factor 1 (MRF-1), is an estrogen receptor alpha (ER alpha)-interacting protein that is expressed abundantly in cardiovascular tissues and suppresses ER alpha-induced transactivation. It also associates with thyroid receptor alpha (TR alpha) and retinoid X receptor alpha (RXR alpha) in a ligand-dependent manner, and with ER beta, androgen receptor (AR), and the retinoic acid receptor (RAR) in a ligand-independent manner. ARID5A functions as a negative regulator of RORgamma-induced Th17 cell differentiation and may be involved in the pathogenesis of rheumatoid arthritis (RA). Moreover, it is an important transcriptional partner of the transcription factor sex determining region Y (SRY)-box protein 9 (Sox9) in stimulation of chondrocyte-specific transcription. Meanwhile, ARID5A plays an important role in promotion of inflammatory processes and autoimmune diseases. It works as a unique RNA binding protein, which stabilizes interleukin-6 (IL-6) but not tumor necrosis factor-alpha (TNF-alpha) mRNA through binding to the 3' untranslated region (UTR) of IL-6 mRNA, and inhibits the destabilizing effect of regnase-1 on IL-6 mRNA. ARID5A contains an AT-rich DNA-interacting domain (ARID, also known as BRIGHT).

ARID/BRIGHT DNA binding domain of lysine-specific demethylase KDM5C and KDM5D; This group includes KDM5C and KDM5D, both of which belong to the JARID subfamily within the JmjC proteins. KDM5C, also called histone demethylase JARID1C, Jumonji/ARID domain-containing protein 1C, protein SmcX, or protein Xe169, is a H3K4 trimethyl-histone demethylase that catalyzes demethylation of H3K4me3 and H3K4me2 to H3K4me1. It plays a role in neuronal survival and dendrite development. KDM5C defects are associated with X-linked mental retardation (XLMR). KDM5D, also called histocompatibility Y antigen (H-Y), histone demethylase JARID1D, Jumonji/ARID domain-containing protein 1D, or protein SmcY, is a male-specific antigen that shows a demethylase activity specific for di- and tri-methylated histone H3K4 (H3K4me3 and H3K4me2), and has a male-specific function as a histone H3K4 demethylase by recruiting a meiosis-regulatory protein, MSH5, to condensed DNA. KDM5D directly interacts with a polycomb-like protein Ring6a/MBLR, and plays a role in regulation of transcriptional initiation through H3K4 demethylation. Both KDM5C and KDM5D contain the catalytic JmjC domain, a JmjN domain, an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a C5HC2 zinc finger, as well as two plant homeodomain (PHD) fingers.

ARID/BRIGHT DNA binding domain of lysine-specific demethylase 5B (KDM5B); KDM5B, also called cancer/testis antigen 31 (CT31), histone demethylase JARID1B, Jumonji/ARID domain-containing protein 1B (JARID1B), PLU-1, or retinoblastoma-binding protein 2 homolog 1 (RBP2-H1 or RBBP2H1A), is a member of the JARID subfamily within the JmjC proteins. It has a restricted expression pattern in the testis, ovary, and transiently in the mammary gland of the pregnant female and has been shown to be upregulated in breast cancer, prostate cancer, and lung cancer, suggesting a potential role in tumorigenesis. KDM5B acts as a histone demethylase that catalyzes the removal of trimethylation of lysine 4 on histone H3 (H3K4me3), induced by polychlorinated biphenyls (PCBs). It also mediates demethylation of H3K4me2 and H3K4me1. Moreover, KDM5B functions as a negative regulator of hematopoietic stem cell (HSC) self-renewal and progenitor cell activity. KDM5B has also been shown to interact with the DNA binding transcription factors BF-1 and PAX9, as well as TIEG1/KLF10 (transforming growth factor-beta inducible earlygene-1/Kruppel-like transcription factor 10), and possibly function as a transcriptional corepressor. KDM5B contains the catalytic JmjC domain, a JmjN domain, an AT-rich DNA-interacting domain (ARID, also known as BRIGHT), a C5HC2 zinc finger, as well as three plant homeodomain (PHD) fingers.
