While being in complex I, RIPK1 has also been proved to play a role in the activation of MAP (mitogen-activated protein) kinases such as JNK, ERK and p38. In particular, JNK can be found in both cell death and survival pathways, with its role in the cell death process being suppressed by activated NF-kB. [5]

TAK1 is a central regulator of cell death and is activated through a diverse set of intra- and extracellular stimuli. TAK1 regulates cell survival not solely through NF-κB but also through NF-κB-independent pathways such as oxidative stress and receptor-interacting protein kinase 1 (RIPK1) kinase activity-dependent pathway.

Recent studies have shown substantial interplay between the apoptosis and necroptosis pathways. At multiple stages of their respective signalling cascades, the two pathways can regulate each other. The best characterized example of this co-regulation is the ability of caspase 8 to inhibit the formation of the necrosome by cleaving RIPK1.
The protein encoded by this gene is a death domain (CARD/DD)-containing protein and has been shown to induce cell apoptosis. Through its CARD domain, this protein interacts with, and thus recruits, caspase 2/ICH1 to the cell death signal transduction complex that includes tumor necrosis factor receptor 1 (TNFR1A), RIPK1/RIP kinase, and numbers of other CARD domain-containing proteins.
About 25 years after a pregnant woman was found strangled to death in a Toronto parking lot, authorities have arrested and charged a suspect. In a Feb. 7 press release announcing the arrest of 50 ...
Similarly, both dual-specificity MAP kinase phosphatases and MAP-specific tyrosine phosphatases bind to MAP kinases through the same docking site. [34] [35] D-motifs can even be found in certain MAPK pathway regulators and scaffolds (e.g. in the mammalian JIP proteins). [citation needed] Other, less well characterised substrate-binding sites ...
