Homodimer (PubMed:29440439, PubMed:29681455). Interacts (via RIP homotypic interaction motif) with RIPK3 (via RIP homotypic interaction motif); this interaction induces RIPK1 phosphorylation and formation of a RIPK1-RIPK3 necroptosis-inducing complex (PubMed:11734559, PubMed:29883609, PubMed:19524512, PubMed:10358032, PubMed:29681455). Upon TNF-induced necrosis, the RIPK1-RIPK3 dimer further interacts with PGAM5 and MLKL; the formation of this complex leads to PGAM5 phosphorylation and increase in PGAM5 phosphatase activity (PubMed:22265414). Interacts (via the death domain) with TNFRSF6 (via the death domain) and TRADD (via the death domain) (PubMed:8612133). Is recruited by TRADD to TNFRSF1A in a TNF-dependent process (PubMed:24130170). Binds RNF216, EGFR, IKBKG, TRAF1, TRAF2 and TRAF3 (PubMed:8612133, PubMed:9927690, PubMed:11854271, PubMed:11116146). Interacts with BNLF1 (PubMed:10409763). Interacts with SQSTM1 upon TNF-alpha stimulation (PubMed:10356400). May interact with MAVS/IPS1 (PubMed:16127453). Interacts with ZFAND5 (PubMed:14754897). Interacts with RBCK1 (PubMed:17449468). Interacts with ZBP1 (By similarity). Interacts with BIRC2/c-IAP1, BIRC3/c-IAP2 and XIAP/BIRC4 (PubMed:21931591). Interacts (via kinase domain) with DAB2IP (via Ras-GAP domain); the interaction occurs in a TNF-alpha-dependent manner (PubMed:17389591, PubMed:15310755). Interacts with ARHGEF2 (PubMed:21887730). Interacts (via protein kinase domain) with RFFL; involved in RIPK1 ubiquitination (PubMed:18450452). Interacts with RNF34; involved in RIPK1 ubiquitination (Ref. 34). Interacts with TICAM1 and this interaction is enhanced in the presence of WDFY1 (PubMed:25736436). Interacts with PELI1 (PubMed:29883609). Interacts (via death domain) with CRADD (via death domain); the interaction is direct (PubMed:9044836). Component of complex IIa composed of at least RIPK1, FADD and CASP8 (By similarity). Component of the AIM2 PANoptosome complex, a multiprotein complex that drives inflammatory cell death (PANoptosis) (By similarity). Interacts with MAP3K7, CFLAR, CASP8, FADD and NEMO (By similarity). (Microbial infection) Interacts with mumps virus protein SH; this interaction inhibits downstream NF-kappa-B pathway activation. (Microbial infection) Interacts with Murid herpesvirus 1 protein RIR1. (Microbial infection) Interacts (via RIP homotypic interaction motif) with herpes simplex virus 1/HHV-1 protein RIR1/ICP6 (via RIP homotypic interaction motif); this interaction prevents necroptosis activation. (Microbial infection) Interacts (via RIP homotypic interaction motif) with herpes simplex virus 2/HHV-2 protein RIR1/ICP10 (via RIP homotypic interaction motif); this interaction prevents necroptosis activation.
