Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: single-stranded DNA binding.
There is experimental evidence that it is involved in the biological process: regulation of chromatin silencing.
7 alleles are reported.
No phenotypic data is available.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: PUR-alpha/beta/gamma, DNA/RNA-binding.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 12-24 hour embryonic stages, during late larval stages, at stages throughout the pupal period, in adult male stages.
