Protein CBFA2T3 (core-binding factor, runt domain, alpha subunit 2; translocated to, 3) is a protein that in humans is encoded by the CBFA2T3 gene.^[5][6]

Function

The t(16;21)(q24;q22) translocation is a rare but recurrent chromosomal abnormality associated with therapy-related myeloid malignancies. The translocation produces a chimeric gene made up of the 5'-region of the AML1 gene fused to the 3'-region of this gene. In addition, this gene is a putative breast tumor suppressor. Two transcript variants encoding different isoforms have been found for this gene, and a brefeldin A-sensitive association of RII-alpha protein with one of the isoforms has been demonstrated in the Golgi apparatus.^[6]

Interactions

CBFA2T3 has been shown to interact with:

• HDAC1,^[7][8]
• HDAC3,^[7][8]
• LDB1,^[9]
• PRKAR2A,^[10]
• RUNX1T1^[7][11] and
• TAL1,^[9] and
• TCF3.^[9]
