Transcriptional repressor regulating the expression of a number of genes including SP1 target genes. Probably functions through recruitment of HDAC1 a histone deacetylase involved in chromatin silencing.

Biochemical analysis of the BAHD1-associated multiprotein complex identifies MIER proteins as novel partners of BAHD1 and suggests that BAHD1-MIER interaction forms a hub for histone deacetylases and methyltransferases PMID: 26938916
Insulin and IGF-1 alter the subcellular localization of MIER1alpha in breast carcinoma cells. PMID: 26281834
nuclear targeting of MIER1alpha requires an intact ELM2 domain and is dependent on interaction with HDAC1/2 PMID: 24376786
the first immunohistochemical study of the MIER1alpha protein expression pattern in human tissues, is reported. PMID: 23277184
Differential splicing alters subcellular localization of the alpha but not beta isoform of the MIER1 transcriptional regulator in breast cancer cells PMID: 22384264
Results demonstrate that alternate use of a facultative intron regulates the subcellular localization of hMI-ER1 proteins and this may have important implications for hMI-ER1 function. PMID: 12242014
we investigated the role of hMI-ER1alpha and hMI-ER1beta in the regulation of transcription.We demonstrate that this repressor activity is due to interaction and recruitment of a trichostatin A-sensitive histone deacetylase 1 (HDAC1). PMID: 12482978
the association of hMI-ER1 with Sp1 represents a novel mechanism for the negative regulation of Sp1 target promoters PMID: 15117948
Loss of nuclear MI-ER1 alpha might contribute to the development of invasive breast carcinoma PMID: 18665173
Ubiquitously expressed, but at very low levels. However, consistent level of expression are observed in heart, testis, thyroid, ovary and adrenal gland. Transcripts are up-regulated in breast carcinoma cell lines and tumor.
