NF-IB Protein Definition
Expressed as 3 alternative isoforms by human NFIB Gene (CTF/NF-I Family), nuclear NF-IB Protein contains an N-terminal DNA-binding domain, a C-terminal transactivation domain, and a DWA/MH1 domain. NF-IB binds TTGGCNNNNNGCCAA DNA palindromes in viral and cellular promoters as a homodimeric factor capable of activating transcription and replication. Truncated 188-aa NFIB3 protein contains only the N-terminal DNA-binding domain, forms heterodimers with other NFI proteins, reduces their ability to bind DNA, and may repress transcription by other NFI proteins.
