Localization patterns of Zscan4 correlate with Pol II-mediated transcription activity in GV oocytes. (A) SN- and NSN-type GV oocytes were immunostained for Pol2(S2P): RNA polymerase II CTD repeat (phospholylated Ser2), a marker for active transcriptional elongation. Weak Pol2(S2P) in Zscan4-spotty SN-type oocytes(top, n = 27/27), intense Pol2(S2P) in Zscan4-diffusive SN-type oocytes (middle, n = 2/2), intense Pol2(S2P) in Zscan4-diffusive NSN-type oocytes (bottom, n = 3/3). (B) SN- and NSN-type GV oocytes were immunostained for Pol2(S5P): RNA polymerase II CTD repeat (phospholylated Ser5), a marker for active transcriptional initiation.
