BEX4 brain expressed X-linked 4 [Homo sapiens (human)] - Gene

Summary

Official Symbol: BEX4provided by HGNC
Official Full Name: brain expressed X-linked 4provided by HGNC
Primary source: HGNC:HGNC:25475
See related: Ensembl:ENSG00000102409 MIM:300692; AllianceGenome:HGNC:25475
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: BEXL1
Summary: This gene is a member of the brain expressed X-linked gene family. The proteins encoded by some of the other members of this family act as transcription elongation factors which allow RNA polymerase II to escape pausing during elongation. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Aug 2011]
Expression: Ubiquitous expression in brain (RPKM 111.7), thyroid (RPKM 67.9) and 23 other tissues See more

Aberrant brain-expressed X-linked 4 (BEX4) expression is a novel prognostic biomarker in gastric cancer.
Title: Aberrant brain-expressed X-linked 4 (BEX4) expression is a novel prognostic biomarker in gastric cancer.
these results suggest that the oncogenicity of BEX4 is conferred by PLK1-mediated phosphorylation, and thus, the BEX4-PLK1 interaction is a novel oncogenic signal that enables the acquisition of chromosomal aneuploidy.
Title: Oncogenic potential of BEX4 is conferred by Polo-like kinase 1-mediated phosphorylation.
BEX4 positively regulated the expression of OCT4, silencing of which reduced the proliferation of A549 and H1975cells with over-expressed BEX4.
Title: mTOR up-regulation of BEX4 promotes lung adenocarcinoma cell proliferation by potentiating OCT4.
Study provides evidence that BEX4 functions as tumor suppressor by inhibiting proliferation and growth of oral squamous cell carcinoma (OSCC). Decreased BEX4 contributes to the increased proliferative propensity of OSCC.
Title: Decreased brain-expressed X-linked 4 (BEX4) expression promotes growth of oral squamous cell carcinoma.
BEX4 overexpression causes an imbalance between TUB acetylation and deacetylation by SIRT2 inhibition and induces oncogenic aneuploidy transformation.
Title: Oncogenic microtubule hyperacetylation through BEX4-mediated sirtuin 2 inhibition.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
