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. Interacts with HDAC1. Part of a complex containing at least CDYL, MIER1, MIER2, HDAC1 and HDAC2. 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. It is uncertain whether Met-1 or Met-55 is the initiator. It is uncertain whether Met-1 or Met-55 is the initiator. Wrong choice of CDS. Probable cloning artifact due to reverse transcription from RNA internal poly-A tracts. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus. Truncated N-terminus. Chimeric cDNA. C-terminal is identical to the product of the WLS gene. Wrong choice of CDS.
