Function
- recognizes & binds the palindromic sequence 5'-TTGGCNNNNNGCCAA-3' present in viral & cellular promoters & in the origin of replication of adenovirus type 2
- these proteins are individually capable of activating transcription & replication
- binds DNA as a homodimer
- phosphorylated upon DNA damage, probably by ATM or ATR
Structure
- belongs to the CTF/NF-I family
- contains 1 CTF/NF-I DNA-binding domain
