Abstract:
We have cloned from a cDNA library of neuronal derivatives of retinoic-acid-induced embryonic carcinoma cells a nuclear receptor that may be involved in the control of late neurogenesis and early neuronal differentiation. The receptor which is practically identical in sequence with germ cell nuclear factor, has been designated neuronal cell nuclear factor (NCNF). NCNF is exclusively expressed in the neuronal derivatives of PCC7-Mz1 cells, with the expression beginning within hours of exposure to retinoic acid. In the developing mouse brain, NCNF is expressed in the marginal zones of the neuroepithelium which are known to contain young postmitotic neurons. NCNF binds to the DR0 sequence thereby silencing transcription. Because NCNF does not recognize hormone response elements of other nuclear receptors tested and does not heterodimerize with these, it probably binds exclusively as a homodimer. NCNF may induce neuronal differentiation by repressing the activity of genes that permit cell fates other than the neuronal one.
