Genes involved and Proteins

Gene NameTAL1 (T-cell acute leukemia 1)
Location 1p33
Dna / Rna complex alternate splicing
Protein contains a basic Helix-Loop-Helix (DNA binding) domain; cforms heterodimers; transcription factor; role in haematopoietic cell differentiation
Gene NameTCTA (T-cell leukemia translocation-associated gene)
Location 3p21.31
Protein contains a hydrophobic domain; may be a membrane associated protein

Result of the chromosomal anomaly

Hybrid gene
Description TCTA and TAL1 are in opposite direction
Fusion Protein
Description it may be that the promoting regions from TCTA disregulate TAL1 expression


Cloning and characterization of TCTA, a gene located at the site of a t(1;3) translocation.
