Hypophosphorylated Thor/4E-BP competes with eIF4G1 to interact with eIF4E1; insulin stimulated Akt1 or Tor phosphorylation of Thor/4E-BP causes dissociation of the complex allowing eIF4G1 to bind and consequent initiation of translation.
Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70, corresponding to the hyperphosphorylated form, impairs its ability to prevent the interaction between eIF4G1 and eIF4E1, without affecting its interaction with free eIF4E1 (PubMed:14645523, PubMed:25702871). Phosphorylated in rtesponse to insulin (PubMed:11389445). Phosphorylation at Thr-46 is regulated by Tor and constitutes the major phosphorylation event that regulates activity (PubMed:14645523).
The YXXXXLphi motif mediates interaction with eIF4E1 (PubMed:11389445). Compared to other members of the family this YXXXXLphi is atypical and interaction with eIF4E1 is weaker (PubMed:11389445).

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Thor transcripts are detected at all stages on northern blots and are strongly induced upon infection. They are observed by in situ hybridization in the embryonic central nervous system and in the reproductive systems of males and females. They are observed third instar male testis and in adult female ovaries.

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 JBrowse 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.
The Thor translational inhibitor is a relevant foxo target gene. Cellular stress may activate foxo and inhibit growth through the action of target genes such as Thor. Transcriptionally downregulated after 2h of insulin stimulation in Kc167 cells. Contains fkh response elements (FHREs) in the genomic upstream or intronic sequences.
Thor participates in host immune defence and connects a translational regulator with innate immunity.
Identified in a screen to find interactors with eIF-4E from a cDNA expression library. When bound to eIF-4E, Thor prevents the integration of eIF-4E into the translationally active eIF-4F complex. Thor may be involved in the translational regulation of specific mRNAs throughout development and adult fly life.
Cg25C is a member of the infection inducible enhancer detector strains.

"l(2)06270" probably corresponds to "Thor"; the P{PZ} insertion in the "l(2)0627006270" allele maps 20bp upstream of the 5' end of the CT9265 transcript of "Thor".
Source for merge of Thor anon-WO0172774.158 was sequence comparison ( date:051113 ).
Ecol\lacZ reporter gene expression from the Thor enhancer trap insertion P{lacW}Thork13517 increases upon infection, and so the gene is named "Thor" after the Nordic legendary character that was often called upon to use his hammer to protect mankind from harm.
