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. 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. Interactions CBFA2T3 has been shown to interact with: HDAC1, HDAC3, LDB1, PRKAR2A, RUNX1T1 and TAL1, and TCF3. References Further reading External links Transcription factors Oncogenes
