Function
[KPEL_DROME] Plays an essential role in the Tl receptor signaling pathway that establishes embryonic dorsoventral polarity; the signal directs import of dl into ventral and ventrolateral nuclei, thereby establishing dorsoventral polarity. Tub recruits pll to the plasma membrane and protein-protein interaction activates pll.[1] [2] [3] [4] [TUBE_DROME] Plays an essential role in the Tl receptor signaling pathway that establishes embryonic dorsoventral polarity; the signal directs import of dl into ventral and ventrolateral nuclei, thereby establishing dorsoventral polarity. Tub recruits pll to the plasma membrane and protein-protein interaction activates pll. Also has a role in pupal pattern formation.[5] [6] [7] [8] [9]

Publication Abstract from PubMed
The interaction of the serine/threonine kinase Pelle and adaptor protein Tube through their N-terminal death domains leads to the nuclear translocation of the transcription factor Dorsal and activation of zygotic patterning genes during Drosophila embryogenesis. Crystal structure of the Pelle and Tube death domain heterodimer reveals that the two death domains adopt a six-helix bundle fold and are arranged in an open-ended linear array with plastic interfaces mediating their interactions. The Tube death domain has an insertion between helices 2 and 3, and a C-terminal tail making significant and indispensable contacts in the heterodimer. In vivo assays of Pelle and Tube mutants confirmed that the integrity of the major heterodimer interface is critical to the activity of these molecules.
