Association of histone H4 genes with the mammalian testis-specific H1t histone gene.
Mouse and human H4 genes associated with the testis-specific H1t gene were isolated from genomic libraries and were sequenced. The deduced amino acid sequences are identical to other mouse or human H4 histones, but the genes differ significantly in their nucleotide sequences. Both the human and the mouse genes are located on the same DNA strand compared with the H1t gene. In contrast to this identical transcriptional orientation of H1t and its neighboring H4 gene in mouse and man, an H4 gene with the opposite orientation has been described in the vicinity of the rat H1t gene. Northern blot analysis of RNA from testicular cells separated by centrifugal elutriation, S1 nuclease mapping, and reverse transcriptase polymerase chain reaction (RT-PCR) amplification show that both the murine and human H4 genes, like the H1t gene, are expressed in testicular cells, whereas the H4 genes, in contrast to the H1t gene, are expressed in nontesticular human and mouse cell culture cells.
