    basic FUNCTION
  • recognizing the palindromic sequence 5'- TTGGCNNNNNGCCAA-3' present in viral and cellular promoters and in the origin of replication of adenovirus type 2
  • being capable of activating transcription and replication
  • play roles in patterning, glial development, cortical cell migration and axon guidance
  • involved in the cooperative regulation of whey acidic protein (WFDC5) gene transcription along with the glucocorticoid receptor and STAT5
  • rearrangement of NFIB might be associated with deep-seated lipomas, such as retroperitoneal or gastro-intestinal lipomas
  • plays an important role in the generation of precerebellar mossy fiber neurons, and may do so at least in part by regulating neurogenesis
  • mesenchymal NFIB-mediated signals are essential for the maturation of distal lung epithelium
    • CELLULAR PROCESS nucleotide, replication

    tumoral fusion translocation    
    t(6;9)(q23.3;p22.3) translocation in adenoid cystic carcinomas (ACC) of the breast and head and neck results in fusions encoding chimeric transcripts predominantly consisting of MYB exon 14 linked to the last coding exon(s) of NFIB
    tumoral fusion      
    in a case of retroperitoneal lipoma, fusion of HMGA2 with NFIB with a t(9;16;19)(p22;q21;q13) and a rearrangement of NFIB and no rearrangement of HMGA2

    ANIMAL & CELL MODELS
  • Nfia and Nfix null mice exhibit no apparent pontine phenotype, implying specificity in the action of NFI family members
  • Nfib-deficient mice possess unique defects in lung maturation and exhibit callosal agenesis and forebrain defects that are similar to, but more severe than, those seen in Nfia-deficient animals
