The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).
Hira transcripts are detected at all stages of development on northern blots but are strongest in adult females, unfertilized eggs, and 0-3hr embryos. Transcripts are ubiquitously distributed in blastoderm embryos. By cellularization, transcript levels decrease significantly. In ovaries, Hira transcripts are first detected in mid stage nurse cells. Later they are detected at high levels in oocytes.

Please Note This section lists cDNAs and ESTs that fall within the genomic extent of the gene model, which may include cDNAs and ESTs of genes within introns, or of overlapping genes. Please see JBrowse for alignment of the cDNAs and ESTs to the gene model.
For each fully sequenced cDNA the DGRC maintains various forms of the cDNA (e.g tagged or untagged) in several different host vectors for subsequent cloning and expression in Drosophila and Drosophila cell lines.
polyclonal
Mutation in Hira affects maternal histone incorporation in the male pronucleus.
Maternally provided Hira is required for a late stage of sperm chromatin re-modelling.
