Background
This gene encodes a zinc finger domain-containing protein that functions as a regulator of transcription. The encoded proteins binds to its own promoter as well as to that of several target genes. Activity of this protein is important in the regulation of embryonic development. Mutations in this gene have been found in individuals with autosomal dominant mental retardation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014],
Function
alternative products:Experimental confirmation may be lacking for some isoforms,caution:This protein was first known as suppressin (characterized in bovine neuroendocrine and immune cells). However, according to PubMed:9773984, it is uncertain whether it corresponds really to the suppressin also described in Ref.3. DEAF1 has been described as a nuclear dimeric protein and suppressin as a secreted monomeric protein.,disease:Defects in DEAF1 could confer a growth advantage to the mutated cell that may have implications for the development and progression of neoplasia, e.g. in the case of colorectal adenocarcinomas (CRC).,function:Transcription factor that binds to sequence with multiple copies of TTC[CG]G present in its own promoter and that of the HNRPA2B1 gene. Down-regulates transcription of these genes. Binds to the retinoic acid response element (RARE) AGGGTTCACCGAAAGTTCA. Activates t

Cellular localization
[Isoform 1]: Nucleus. Cytoplasm. Cytoplasmic in non-mucinous colorectal carcinoma. When expressed alone, localized almost exclusively in the nucleus but, when expressed with isoform 4, nuclear expression decreases to 32% and cytoplasmic expression increases by 270%.; [Isoform 2]: Secreted. Secreted in some cell types.; [Isoform 3]: Secreted. Secreted in some cell types.; [Isoform 4]: Cytoplasm. Nucleus. When expressed alone, localizes mainly in the cytoplasm but, when expressed with isoform 1, nuclear localization is enhanced.
Tissue expression
Expressed in various tissues and cells such as in peripheral mononuclear cells and hormone-secreting pituitary cells. Expression in pancreatic lymph nodes of patients with type 1 diabetes is 20 times higher than in healthy controls. Highly expressed in fetal and adult brain.
