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: DIF2; IEX1; PRG1; DIF-2; GLY96; IEX-1; IEX-1L
Summary: This gene functions in the protection of cells from Fas- or tumor necrosis factor type alpha-induced apoptosis. Partially degraded and unspliced transcripts are found after virus infection in vitro, but these transcripts are not found in vivo and do not generate a valid protein. [provided by RefSeq, Jul 2008]

IER3 (IEX-1) dysregulation serves as a potential prognostic factor in acute myeloid leukemia patients.
Title: IER3 (IEX-1) dysregulation serves as a potential prognostic factor in acute myeloid leukemia patients.
Overexpression of GAS5 enhanced the sensitivity of cervical cancer cells to radiation treatment via up-regulating IER3 through miR-106b.
Title: LncRNA GAS5 confers the radio sensitivity of cervical cancer cells via regulating miR-106b/IER3 axis.
Our findings suggest for the first time that the increased expression of IER3 protein may promote the aggressive progression of BCa. Importantly, IER3 may be a potential prognostic marker for BCa patients.
Title: Increased expression of immediate early response gene 3 protein promotes aggressive progression and predicts poor prognosis in human bladder cancer.
we determined the molecular mechanism responsible for IER3 degradation, involving a ternary complex of IER3, MDM2 and FHL2, which may contribute to cervical tumor growth. Furthermore, we demonstrated that FHL2 serves as a scaffold for E3 ligase and its substrate during the ubiquitination reaction, a function that has not been previously reported for this protein
Title: Scaffold protein FHL2 facilitates MDM2-mediated degradation of IER3 to regulate proliferation of cervical cancer cells.
Analysis of consensus EGR-binding elements (EBEs) showed that the immediate early response 3 gene (IER3) is a novel transcriptional target gene of EGR2 as confirmed by the luciferase assay, electrophoretic mobility-shift assay (EMSA), chromatin immunoprecipitation (ChIP), and western blot analysis.
Title: EGR2 is a gonadotropin-induced survival factor that controls the expression of IER3 in ovarian granulosa cells.
Study characterized IEX-1's expression and function in rheumatoid arthritis synovial fibroblasts and showed that IEX-1 is highly expressed in RA-SFs and negatively regulates RA-SF activation.

interleukin-1beta (IL-1beta)-induced IER3 expression is mediated by the ERK1/2 target, transcription factor Elk-1.
Title: Transcription factor Elk-1 participates in the interleukin-1β-dependent regulation of expression of immediate early response gene 3 (IER3).
findings suggest that IER3 is a putative tumor suppressor in the cervix, and the c-Ab1/p73beta/IER3 axis is a novel and crucial signaling pathway that confers etoposide chemosensitivity.
Title: IER3 is a crucial mediator of TAp73β-induced apoptosis in cervical cancer and confers etoposide sensitivity.
High expression of IER3 is associated with hepatocarcinoma.

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.
