Chromosomal localization of PHOX2B during M-phase is disrupted in disease-associated mutants.

ABSTRACT: In the M-phase, the nuclear membrane is broken down, nucleosomes are condensed as mitotic chromosomes, and transcription factors are generally known to be dislocated from their recognition sequences and dispersed to the cytoplasm. However, some transcription factors have recently been reported to remain on mitotic chromosomes and facilitate the rapid re-activation of the target genes in early G1-phase. Paired-like homeobox 2B (PHOX2B) is a transcription factor exhibiting chromosomal localization during M-phase. PHOX2B mutations are associated with congenital central hypoventilation syndrome, Hirschsprung disease, and neuroblastoma. In this study, we investigated PHOX2B chromosomal localization during M-phase through immunostaining and fluorescence recovery after photobleaching analysis to
