HMGB4 Antibody

High mobility group protein B4 (HMGB4) is a transcription factor that plays a role in spermatogenesis. During spermatogenesis, HMGB4 is present in the euchromatin of late pachytene spermatocytes and haploid round spermatids, whereas stronger expression is observed during the elongation phase, where it localizes to the basal pole of the nucleus in a manner mutually exclusive with H1FNT (H1T2) localized at the apical pole.
