• Immunogen: A synthesized peptide derived from human RIPK3 around the phosphorylation site of Ser227.
• Conjugation: Unconjugated
• Fragment: Fab fragment
• Post Translational Modifications: RIPK1 and RIPK3 undergo reciprocal auto- and trans-phosphorylation. Phosphorylation of Ser-199 plays a role in the necroptotic function of RIPK3. Phosphorylation at Ser-227 is required for binding MLKL. Phosphorylation at Thr-182 is important for its kinase activity, interaction with PELI1 and PELI1-mediated 'Lys-48'-linked polyubiquitination and for its ability to mediate TNF-induced necroptosis.Polyubiquitinated with 'Lys-48' and 'Lys-63'-linked chains by BIRC2/c-IAP1 and BIRC3/c-IAP2, leading to activation of NF-kappa-B. Polyubiquitinated with 'Lys-48'-linked chains by PELI1 leading to its subsequent proteasome-dependent degradation. Ubiquitinated by STUB1 leading to its subsequent proteasome-dependent degradation.
• Subunit Structure: Interacts (via RIP homotypic interaction motif) with RIPK1 (via RIP homotypic interaction motif); this interaction induces RIPK1 phosphorylation and formation of a RIPK1-RIPK3 necrosis-inducing complex. 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. Interacts with MLKL; the interaction is direct. Binds TRAF2 and is recruited to the TNFR-1 signaling complex. Interacts with PYGL, GLUL and GLUD1; these interactions result in activation of these metabolic enzymes. Interacts with BIRC2/c-IAP1, BIRC3/c-IAP2 and XIAP/BIRC4. Interacts with ARHGEF2. Interacts with PELI1 (via atypical FHA domain); the phosphorylated form at Thr-182 binds preferentially to PELI1. Interacts with BUB1B, TRAF2 and STUB1. Interacts with ZBP1 (By similarity).
• Similarity: Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family.
• Subcellular Location: Cytoplasm>Cytosol. Cell membrane. Mitochondrion.
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Immunohistochemistry (IHC)

(At 1/100 staining Rat heart tissue by IHC-P. The sample was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The sample was then blocked and incubated with the primary antibody at 4 degree C overnight. An HRP conjugated anti-Rabbit antibody was used as the secondary antibody.)

Related Product Information for anti-RIPK3 antibody

Essential for necroptosis, a programmed cell death process in response to death-inducing TNF-alpha family members. Upon induction of necrosis, RIPK3 interacts with, and phosphorylates RIPK1 and MLKL to form a necrosis-inducing complex. RIPK3 binds to and enhances the activity of three metabolic enzymes: GLUL, GLUD1, and PYGL. These metabolic enzymes may eventually stimulate the tricarboxylic acid cycle and oxidative phosphorylation, which could result in enhanced ROS production.

NCBI Description

The product of this gene is a member of the receptor-interacting protein (RIP) family of serine/threonine protein kinases, and contains a C-terminal domain unique from other RIP family members. The encoded protein is predominantly localized to the cytoplasm, and can undergo nucleocytoplasmic shuttling dependent on novel nuclear localization and export signals. It is a component of the tumor necrosis factor (TNF) receptor-I signaling complex, and can induce apoptosis and weakly activate the NF-kappaB transcription factor. [provided by RefSeq, Jul 2008]
