CREB-1 (Ca2+/cAMP response element binding protein-1)
Ca2+/cAMP response element binding (CREB-1) protein is a transcription factor that regulates cell growth, homeostasis and survival. A TM phosphorylates CREB at
Ser111 in response to IR. This, in turn, triggers CK-2 dependent phosphorylation of
Ser108 and CK1 dependent phosphorylatio~ ofSer114 and Ser117. The phosphorylation of Ser 114 and Ser 117 by CK1 renders CREB permissive for ATM dependent phosphorylation at Ser121 (Shanware et al., 2007). Ser121 phosphorylation causes a decrease in CREB transactivation potential and reduces interaction between CREB and its transcriptional coactivator, CREB binding protein (CBP). Deregulation of ATM-CREB pathway may be a contributing factor to neurodegeneration seen in A-T patients (Dodson and Tibbetts, 2006; Shi et al.,
2004). …show more content…

FANCA (Fanconi anemia, complementation group A)
Fanconi anemia, complementation group A, also known as F ANCA, is a protein which in humans is encoded by the F ANCA gene, mutations in which are the most common cause of Fanconi anemia. F ANCA is phosphorylated after DNA damage and localizes to chromatin. ATR phosphorylates FANCA at Ser1449 after DNA damage but not in S-phase. This phosphorylation is further required for the ubiquitination ofF ANCA and regulates chromatin organization by FA proteins.
Hence Ser1449 mutant fails to completely correct a variety ofF A associated phenotypes (Collins et al., 2009; Wang and D'Andrea, 2004).
