Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: unfolded protein binding.
It is reported to be involved in the biological process: protein folding.
5 alleles are reported.
The phenotypes of these alleles are annotated with: medial longitudinal fascicle; ventral nerve cord commissure; trichogen cell; intermediate longitudinal fascicle; ventral nerve cord; mesothoracic tergum.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: Calreticulin/calnexin; Calreticulin/calnexin, P; Calreticulin/calnexin, conserved site; Concanavalin A-like lectin/glucanase; Concanavalin A-like lectin/glucanase, subgroup.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 00-18 hour embryonic stages, at stages throughout the pupal period.
