Myd88 (Myd88) encodes an adaptor protein involved in in the Toll pathway functioning downstream of the product of Tl and upstream of the product of tub. Toll pathway is a signaling cascade that plays a key role in various developmental and immune processes, notably embryonic dorsoventral patterning and regulation of antimicrobial peptides.

Mitogen-activated protein kinase kinase kinase 7; Component of a protein kinase signal transduction cascade. Mediator of TGF-beta signal transduction. Responsible for activation of the JNK MAPK pathway (basket, bsk and hemipterous, hep) in response to LPS. Component of the NF-kappa-B pathway; relish-mediated JNK inhibition involves proteasomal degradation of Tak1; certain targets of Relish that are induced during immune responses may facilitate destruction of Tak1 and switch off the JNK cascade. Participates in diverse roles such as control of cell shape and regulation of apoptosis.

TAK1-associated binding protein 2 (Tab2) encodes a protein with an ubiquitin binding domain. It interacts with the product of Tak1, a MAP kinase kinase kinase involved the activation of the immune deficiency, JNK and Grindelwald-Eiger pathways.

Tumor necrosis factor receptor superfamily member wengen; Receptor for egr. Involved in induction of apoptosis by triggering JNK signaling. Mediates the tumor suppressor activity of egr which eliminates oncogenic cells from epithelia, thereby maintaining epithelial integrity. Following UV-induced epidermal damage, binds to egr released from apoptotic epidermal cells and plays a role in development of thermal allodynia, a responsiveness to subthreshold thermal stimuli which are not normally perceived as noxious. Together with Moe, involved in control of axon targeting of R8 and R2-R5 ph [...]

Female-specific protein transformer; Member of the regulatory pathway controlling female somatic sexual differentiation, regulated by Sxl. Activates dsx female-specific splicing by promoting the formation of a splicing enhancer complex which consists of tra, tra2 and sr proteins. Together with tra-2, plays a role in switching fru splicing from the male-specific pattern to the female-specific pattern through activation of the female-specific fru 5'-splice site. No known function in males.

Dual specificity mitogen-activated protein kinase kinase hemipterous; Required for the epithelial cell sheet movement called dorsal closure (DC), which allows establishment of the dorsal epidermis. Controls the expression in the dorsal epithelium edges of another dorsal closure gene, puckered (puc). Phosphorylates and activates the MAP kinase bsk; bsk signal transduction pathway mediates an immune response and morphogenesis; Belongs to the protein kinase superfamily. STE Ser/Thr protein kinase family. MAP kinase kinase subfamily.

Transformer-2 sex-determining protein; Required for female sex determination in somatic cells and for spermatogenesis in male germ cells. Positive regulator of female- specific splicing and/or polyadenylation of doublesex (dsx) pre-mRNA. Splicing requires an enhancer complex, dsxRE (dsx repeat element: which contains six copies of a 13-nucleotide repeat and a purine-rich enhancer (PRE)). DsxRE is formed through cooperative interactions between tra, tra2 and the sr proteins, and these interactions require both the repeat sequences and PRE. PRE is required for specific binding of tra2 to [...]

Death-associated inhibitor of apoptosis 1; Anti-apoptotic protein which functions as a caspase regulator, using its E3 ubiquitin-protein ligase activity to smother caspase activity. Binds, ubiquitinates and inactivates initiator caspase Dronc, and effector caspases Drice and Dcp-1. Acts as a Nedd8- E3 ubiquitin-protein ligase for Drice. Suppresses apoptosis by targeting the apoptosome for ubiquitination and inactivation. Plays an important role in cell motility. Overexpression suppresses rpr and hid- dependent cell death in the eye. Interaction of Diap1 with Dronc is required to suppre [...]

BIR repeat containing ubiquitin-conjugating enzyme (Bruce) encodes a BIR domain containing anti-apoptotic protein of the inhibitor of apoptosis (IAP) protein family. It blocks apoptosis in part by binding to and ubiquitylating pro-apoptotic proteins such as the product of rpr. Bruce mutants are viable, but are vulnerable to apoptosis and show defects in spermatid differentiation.
