Summary: Enables Notch binding activity and ubiquitin protein ligase activity. Involved in several processes, including Notch receptor processing; proteasome-mediated ubiquitin-dependent protein catabolic process; and regulation of signal transduction. Located in cytosol and nucleus. Is expressed in organism. Orthologous to human DTX1 (deltex E3 ubiquitin ligase 1); DTX2 (deltex E3 ubiquitin ligase 2); and DTX4 (deltex E3 ubiquitin ligase 4).

REVIEW: Role of the Heterogeneous Nuclear Ribonucleoprotein Hrp48 and Deltex in the Regulation of Notch Signaling
Title: Regulation of Notch Signaling in Drosophila melanogaster: The Role of the Heterogeneous Nuclear Ribonucleoprotein Hrp48 and Deltex.
Dx is involved in the cytoplasmic relocalization of Eiger from the cell membrane, thereby influencing Eiger-mediated JNK-activation process.
Title: Deltex interacts with Eiger and consequently influences the cell death in Drosophila melanogaster.
coexpression of Dx and Hrp48 activates JNK pathway to induce cell death in eye disc of Drosophila melanogaster.
Title: Synergistic interaction of Deltex and Hrp48 leads to JNK activation.
we observed that Dx together with Hrp48 can regulate Notch signaling in an Sxl-independent manner. In addition, Dx and Hrp48 displayed a synergistic effect on caspase-mediated cell death. Our results suggest that Dx and Hrp48 together negatively regulate Notch signaling in Drosophila melanogaster.

Study identified a network of competing endocytic routes mediated by Su(dx) and Dx that positively and negatively regulate N activation; have distinct requirements for ligands, membrane sterol, and endosomal trafficking components; and have different temperature sensitivities.
Title: Compensatory flux changes within an endocytic trafficking network maintain thermal robustness of Notch signaling.
It was shown that Shrub plays a pivotal rate-limiting step in late endosomal ligand-independent Notch activation, depending on the Deltex-dependent ubiquitinylation state of the receptor.
