spen proteins are expressed in most cell types starting in stage 3 embryonic nuclei. Expression continues through the rest of embryogenesis, and is concentrated in nuclei. Higher levels of expression are detected in the epidermis and central nervous system in stage 9-14 embryos.

Please Note FlyBase no longer curates genomic clone accessions so this list may not be complete
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.

Maternally contributed spen protein is required for the specification of cell fate during neuronal and midline development.
Mutants show a homeotic phenotype developing head-like skeletal features in the trunk.
spen does not repress ectopic head-like cuticle by repressing the expression or function of known head-determining genes. Overall orientation not stated: anon-21Ab+ spen+ kis-
Mutants isolated in a screen of the second chromosome identifying genes affecting disc morphology.
Identification: Enhancer trap screen designed to discover genes involved in the cellular aspects of defense mechanisms, as well as in melanotic tumor formation processes linked to blood cell disregulation.
Identified in a genetic screen for modifiers of the phl::tor12D.sev rough eye mutant phenotype.
The ventral naked cuticle of T2, T3 and occasionally A1 of spen- embryos shows an apparent transformation towards head structures.
Identified in a screen for genes whose function is required for the function of Dfd.
