Description Genomic structure of six exons and five introns spanning about 10kb
Transcription Two transcripts of 1.1kb and 1.2kb, expressed mainly in brain and in hemopoietic cell lines. The rat ortholog, Amida, was found highly expressed also in rat testis. TATA less promoter, that can be transactivated in vitro by PU.1 and Ikaros 2. Orientation, minus strand.


Description Conserved protein of 253 amino acids (in man) with two nuclear localization signals (NLS) (n.68-75 and n.190-194) and a DNA binding domain located between the two NLSs.
Expression constitutive
Localisation nuclear
Function Over expression of TFPT/Amida in cultured cells induces arrest in G2-M. Biochemical studies indicate that TFPT/Amida interacts with Cdc2/CDK1 in mitosis and its over expression results in a decrease of Cdc2/CDK1 activity. It is also suggested that the TFPT/Amida DNA binding activity is necessary for cell cycle inhibition and that Amida phophorylation by Cdc2/CDK1, detected in vitro, might decrease this DNA binding activity. Up-regulation of TFPT promotes caspase 9-dependent, p53-independent apoptosis. The pro-apoptotic role of TFPT appears modulated by interaction with specific factors, like Arc and Par-4, which might provide an explanation for the different susceptibility of different cell types to TFPT induced apoptosis.
Homology Very high homology with mouse and rat orthologs.


Somatic Involved in chromosome rearrangement in leukaemia.

Implicated in

Entity Childhood pre-B ALL
Note We detected 8 cases out of 200 : incidence about 4% of childhood pre-B ALL
Cytogenetics Following the position of the two involved genes, E2A on 19p13 and FB1 on 19q13 an appears more likely but a translocation t(19;19)(p13;q13) cannot be yet ruled out. Still pending.
Hybrid/Mutated Gene E2A-FB1
Abnormal Protein Since the chimeric transcripts so far analyzed contain the FB1 sequence fused out of frame to E2A and no truncated E2A protein was detected by Western blot, we suggest that no fusion protein is produced.


Note We detected different joining points in the transcripts of the different analyzed cases indicating different breakpoints in a genomic region spanning exons 15-17 on TCF3 and exons 5-6 on TFPT.
