产品介绍 background:
AT-motif binding factor 1 (ATBF1) binds to the AT-rich core sequence element in the human a-fetoprotein enhancer (1). Alternative splicing generates the ATBF1-A and ATBF1-B (2,3). While ATBF1-A contains a 920-amino acid extension at the N-terminus, both ATBF1-A and ATBF1-B contain 4 DNA-binding homeobox domains (2,3). Additionally, ATBF1-A contains 23 zinc finger motifs while ATBF1-B contains 18 zinc finger motifs (1–3). The N-terminal extension unique to ATBF1-A has transcriptional repressor activity (4). In the small intestine, ATBF1-A inhibits expression of the brushborder enzyme aminopeptidase-N through direct binding to the AT motif element (5). Besides functioning in transcription regulation, ATBF1 also functions in ATPase activity (6). ATPase activity associated with ATBF1-A is DNA/RNA-dependent and requires both homeobox domains and zinc finger motifs (6). ATBF1 is highly expressed in spleen and brain tissues (7). The gene encoding human ATBF1 maps to chromosome 16q22.3-q23.1 (8).

Function:
ATBF1 is a transcription factor that negatively regulates alpha fetoprotein and MYB, transactivates CDKN1A, and may be a tumor suppressor. Loss of ATBF1 is one mechanism that defines the absence of growth control in prostate cancer. Presence of the isoform ABTF1-A is correlated with better prognosis in breast cancer and may also serve as a marker of endocrine responsiveness. 

Subunit:
Interacts with FNBP3 (By similarity). Interacts with PIAS3.

Subcellular Location:
Nuclear

Tissue Specificity:
Not found in normal gastric mucosa but found in gastric carcinoma cells (at protein level).

Post-translational modifications:
Phosphorylated upon DNA damage, probably by ATM or ATR.

Similarity:
Contains 22 C2H2-type zinc fingers.
Contains 4 homeobox DNA-binding domains.
