ATBF1 (AT-binding transcription factor 1)

Identity

Other names	AT motif-binding factor 1
	Alpha-fetoprotein enhancer binding protein
Hugo	ZFHX3
Location	16q22.3-q23.1

DNA/RNA

Description	10 exons, DNA size: 261.32 kb.
Transcription	two isoforms ATBF1-A and ATBF1-B, due to alternative promotor usage combined with alternative splicing, mRNA-size: 11893 bp.

Protein

Description	3703 amino acids; 404 kDa; four homeodomains and 23 zinc fingers including 1 pseudo zinc finger motif, one DEAD and one DEAH box, a RNA and an ATP binding site, two large RS domains and multiple phosphorylation sites.
Expression	Embryonic and neonatal brain.
Localisation	nuclear
Function	Transcription factor that binds to the AT-rich core sequence of the enhancer element of the AFP gene and downregulates AFP gene expression, possibly involved in neuronal differentiation (ATBF1-A).
Homology	mouse atbf1, drosophila zfh2 and C. Elegans ZC 123.3

Mutations

Somatic

Amplification, in one early neural crest derived cell line SJNB-12 under the form of extrachromosomally double minutes, non-syntenic co-amplification with MYC. Absence of ATBF1 expression in alpha-fetoprotein expressing gastric cancer cell lines, lack of ATBF1 expression not due to mutation, deletion or translocation but to strong repression at the transcriptional level.

Implicated in

Disease	Early neural crest derived cell line (SJNB-12).
Prognosis	unknown
Cytogenetics	Several structural and numerical chromosomal aberrations and presence of extrachromosomally double minutes and homogenously staining regions, presence of a reciprocal unbalanced t(8;16)(q24.3;q22.3).
Oncogenesis	Amplification in one neural crest derived cell line (SJNB-12), non-syntenic co-amplification with MYC.
Disease	Alpha-fetoprotein producing gastric cancer cell lines (GCIY and Ist-I).
Prognosis	poor (very malignant and highly metastatic cancer)
Oncogenesis	Alpha-fetoprotein producing cancer cell lines show absence of ATBF1 expression, lack of ATBF1 expression not due to deletion mutation or translocation but to strong repression at the transcriptional level.
