| abstractText | Gene H1t encodes a testis-specific variant of the H1 histone family expressed in pachytene spermatocytes during the meiotic phase of spermatogenesis. Fusions between various upstream fragments of the H1t gene and the chloramphenicol acetyltransferase-encoding reporter gene were analyzed in mouse L cells by both transient and permanent transfection. Expression of the minimal promoter [174 nucleotides (nt) upstream from the transcription start point] was enhanced by sequences extending to nt -693, but was reduced in constructs with kb of upstream sequence. Using synchronized cells, expression was at least twofold higher in growing than in inhibited cells. Thus, the H1t promoter is modulated both positively and negatively by distant upstream sequences, and it displays some of the S-phase-dependent character of a replication-dependent histone. |
