nuclear factor 1 B-type; NF1-B; nuclear factor 1/B; CCAAT-box-binding transcription factor; CTF; nuclear factor I/B; NF-I/B; NFI-B; TGGCA-binding protein (NFIB)

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

Structure

• belongs to the CTF/NF-I family
• contains 1 CTF/NF-I DNA-binding domain

Compartment

nucleus

Alternative splicing

• named isoforms=3
• additional isoforms seem to exist

More general terms

• nuclear factor 1
• phosphoprotein
