DNA/RNA

Transcription

6.7 kb mRNA; coding sequence: 3392 bp

Protein

Description	1130 amino acids
Function	non-DNA-binding transcriptional coactivator; highly regulated; IFN-gamma-inducible; transactivator of the major histocompatibility complex (MHC) class II genes, herein the name; DM and Ii (molecules associated to MHC class II) are also regulated by MHC2TA; MHC2TA also transactivates MHC class I; lymphoid cells of MHC2TA-null mice do not express MHC class II

Implicated in

Note

Entity	t(3;16)(q27;p13)/ BCL6
Disease	non-Hodgkin lymphoma
Prognosis	yet unknown (only 1case available with certainty)
Hybrid/Mutated Gene	5' MHC2TA - 3' BCL6; MHC2TA fuses with the second exon of BCL6
Abnormal Protein	no fusion protein, but promoter exchange
Oncogenesis	BCL6 is a transcription repressor; it is supposed that substitution of the promoter of BCL6 may be responsible for BCL6 deregulation


Entity	bare lymphocyte syndrome (BLS)
Note	at least five complementation groups
Disease	severe immunodeficiency due to failure to express MHC class II genes
