In Northern blots, Hem transcript is detected throughout development, with higher levels in the early embryo, in early first larval instar, and in adults. The expression detected in adults is likely due to ovarian accumulation. Hem transcript is observed in oogenesis and embryogenesis using in situ hybridization. In stage 10 oocytes, the follicle cell and the oocyte express Hem. Hem is ubiquitous in the early embryo. At embryonic stages 7-10, the presumptive procephalic neuroblasts express Hem. Expression is once again ubiquitous in stage 13 embryos. At stage 14, expression is strongest in the pharynx, supraoesophageal ganglion, and the ventral nerve cord. In stage 17 embryos, transcript is detected only in the brain and ventral cord. This pattern persists in the early larval stages.

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 GBrowse 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.
S2 cells treated with dsRNA generated against this gene show reduced phagocytosis of Candida albicans compared to untreated cells.
Hem is necessary for the second round of somatic myoblast fusion in the embryo.
dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.
Five EMS induced alleles were identified in a screen for mutations affecting commissure formation in the CNS of the embryo.
"kette" means "chain" in German.
