Also known as BCAABRCAA1SAP180
Summary
ARID4B (AT-rich interaction domain 4B, HGNC:15550) is a protein-coding gene on chromosome 1q42.3, encoding AT-rich interactive domain-containing protein 4B (Q4LE39). Acts as a transcriptional repressor.
This gene encodes a protein with sequence similarity to retinoblastoma-binding protein-1. The encoded protein is a subunit of the histone deacetylase-dependant SIN3A transcriptional corepressor complex, which functions in diverse cellular processes including proliferation, differentiation, apoptosis, oncogenesis, and cell fate determination. The gene product is recognized by IgG antibody isolated from a breast cancer patient and appears to be a molecular marker associated with a broad range of human malignancies. Alternate transcriptional splice variants encoding different isoforms have been characterized.

Literature-anchored findings (GeneRIF, showing 8)
- Immunohistochemistry analysis showed that the antigen epitope exhibited positive expression in 65% (39 of 60) breast cancer specimens and negative expression in 60 non-cancerous tissues. A novel breast cancer antigen epitope, SSKKQKRSHK, is identified (PMID:15247124)
- Consistent with our genetic analysis and in vivo experiments in our mouse model system, ARID4B expression was also an independent predictor of distant metastasis-free survival in breast cancer patients with ER+ tumors (PMID:22693453)
- ARID4B was significantly elevated in the serum of excessive alcohol users. (PMID:25704570)
- ARID4B overexpression presented in most of primary brain tumors, rather than non-neoplastic brain tissue, and correlated with WHO grades in meningiomas and gliomas. (PMID:27451434)
- our results suggest that ARID4B acts as an oncogene in hepatocellular carcinoma and can therefore serve as a biomarker for the prognoses of patients with hepatocellular carcinoma (PMID:29288040)
- miR-519b-3p directly binds to the 3’ UTR of ARID4B mRNA whose expression was inversely correlated with miR-519b-3p expression. (PMID:29477868)
- ARID4A and ARID4B may play the role as tumor suppressor gene in prostate cancer by inhibiting cell proliferation, migration, and invasion. Moreover, co-downregulation of ARID4A and ARID4B can predict poorer prognosis in prostate cancer, suggesting they might be the novel marker of prognosis and potential therapeutic targets for prostate cancer in human. (PMID:29797600)
- Circ-SMARCA5 suppresses colorectal cancer progression via downregulating miR-39-3p and upregulating ARID4B. (PMID:32807692)

Function. Acts as a transcriptional repressor. May function in the assembly and/or enzymatic activity of the Sin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes. Plays a role in the regulation of epigenetic modifications at the PWS/AS imprinting center near the SNRPN promoter, where it might function as part of a complex with RB1 and ARID4A. Involved in spermatogenesis, together with ARID4A, where it functions as a transcriptional coactivator for AR (androgen receptor) and enhances expression of genes required for sperm maturation. Regulates expression of the tight junction protein CLDN3 in the testis, which is important for integrity of the blood-testis barrier. Plays a role in myeloid homeostasis where it regulates the histone methylation state of bone marrow cells and expression of various genes involved in hematopoiesis. May function as a leukemia suppressor.
Subunit / interactions. Component of a Sin3A corepressor complex consisting of SIN3A, SAP130, SUDS3/SAP45, SAP180, HDAC1 and HDAC2. Interacts with ARID4A. Interacts with AR.
Subcellular location. Nucleus. Cytoplasm.
Tissue specificity. Highly expressed in the testis and in breast, lung, colon, pancreatic and ovarian cancers. Expressed at low levels in the thymus, prostate and ovary.
Domain organisation. The C-terminus mediates interaction with mSin3A corepressor complex. The N-terminus is involved in transcriptional repression by HDAC-independent mechanisms. The ARID domain is involved in stabilizing the mSin3A corepressor complex on DNA.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 146 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
