RIPK1 Protein,Cynomolgus (Active, sf9, GST)

RIPK1 Protein,Cynomolgus (Active, sf9, GST) is the recombinant cynomolgus-derived RIPK1, expressed by Sf9 insect cells , with GST labeled tag. ,

RIPK1, a serine-threonine kinase, stands as a pivotal regulator orchestrating TNF-mediated apoptosis, necroptosis, and inflammatory pathways. Functionally, RIPK1 exhibits kinase-dependent roles in cell death regulation and kinase-independent scaffold functions governing inflammatory signaling and cell survival. As a scaffold protein within the TNF-R1 signaling complex, RIPK1 promotes cell survival by activating the canonical NF-kappa-B pathway. In the context of cell death, RIPK1, through its kinase activity, crucially regulates the assembly of death-inducing complexes—complex IIa (RIPK1-FADD-CASP8) for apoptosis and complex IIb (RIPK1-RIPK3-MLKL) for necroptosis. In normal conditions, RIPK1 inhibits RIPK3-dependent necroptosis by impeding the interaction of TRADD with FADD, thus limiting aberrant CASP8 activation. Additionally, RIPK1 contributes to the inflammatory response by fostering the transcriptional production of pro-inflammatory cytokines like interleukin-6 (IL6). Notably, RIPK1's kinase activity extends to phosphorylating RIPK3, DAB2IP, and participating in ZBP1-induced NF-kappa-B activation in response to DNA damage, highlighting its multifaceted roles in cellular processes.
