Summary: Enables receptor ligand activity and tumor necrosis factor receptor superfamily binding activity. Involved in several processes, including apical protein localization; asymmetric protein localization involved in cell fate determination; and defense response to other organism. Acts upstream of with a positive effect on apoptotic process. Is active in extracellular space and plasma membrane. Is expressed in several structures, including adult head; amnioserosa anlage; anlage in statu nascendi; epithelium; and ganglia. Used to study carcinoma. Human ortholog(s) of this gene implicated in ectodermal dysplasia 1 and tooth agenesis. Orthologous to human TNFSF12 (TNF superfamily member 12); TNFSF12-TNFSF13 (TNFSF12-TNFSF13 readthrough); and EDA (ectodysplasin A). [provided by Alliance of Genome Resources, Dec 2024]

Upregulated TNF/Eiger signaling mediates stem cell recovery and tissue homeostasis during nutrient resupply in Drosophila testis.

such Egr-induced necrosis depends on the catalytic activity of the initiator caspase Dronc and the input from JNK signaling but is independent of their roles in apoptosis. Further mosaic analysis with mutants of scribble (scrib), suggests that Egr/JNK-mediated apoptosis and necrosis establish a two-layered defense system to inhibit the oncogenic growth of scrib mutant cells
Title: Characterization of TNF-induced cell death in Drosophila reveals caspase- and JNK-dependent necrosis and its role in tumor suppression.
These results reveal that Tumour Necrosis Factor mediates exposure of phosphatidylserine (PS), which makes tumor cells selectively sensitive to the action of Defensin remotely secreted from tracheal and fat tissues.
Title: The antimicrobial peptide defensin cooperates with tumour necrosis factor to drive tumour cell death in Drosophila.
Activation of Dmp53 in the growth-depleted territory induces the expression of the Eiger, which activates the JNK stress signaling pathway. JNK-dependent expression of the systemic hormone dILP8 reduces the growth and final size of adjacent territories, the production of Reactive Oxygen Species downstream of JNK and the apoptotic machinery act locally to regulate the proliferation of adjacent epithelial cells.
Title: Eiger/TNFα-mediated Dilp8 and ROS production coordinate intra-organ growth in Drosophila.
Autocrine activation of the adenosine receptor leads to transcriptional upregulation of TNF, which in turn boosts the activity of JNK signalling.
Title: Epithelial cells release adenosine to promote local TNF production in response to polarity disruption.
Activation of epidermal Dronc induces TNF-dependent but effector caspase-independent nociceptive sensitization in the absence of UV. In addition, knockdown of Dronc attenuated nociceptive sensitization induced by full-length TNF/Eiger but not by a constitutively soluble form. UV irradiation induced TNF production in both in vitro and in vivo
Title: Drosophila caspase activity is required independently of apoptosis to produce active TNF/Eiger during nociceptive sensitization.
