Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: protein binding.
There is experimental evidence that it is involved in the biological process: response to hypoxia.
26 alleles are reported.
No phenotypic data is available.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Alpha crystallin/Heat shock protein; HSP20-like chaperone; Heat shock protein Hsp20.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of extremely high expression to a trough of moderate expression.
Peak expression observed during late larval stages, at stages throughout the pupal period.
