Function

Multi-functional protein which regulates not only caspases and apoptosis, but also modulates inflammatory signaling and immunity, mitogenic kinase signaling and cell proliferation, as well as cell invasion and metastasis. Acts as an E3 ubiquitin-protein ligase regulating NF-kappa-B signaling and regulates both canonical and non-canonical NF-kappa-B signaling by acting in opposite directions: acts as a positive regulator of the canonical pathway and suppresses constitutive activation of non-canonical NF-kappa-B signaling. The target proteins for its E3 ubiquitin-protein ligase activity include: RIPK1, RIPK2, RIPK3, RIPK4, CASP3, CASP7, CASP8, IKBKE, TRAF1, and BCL10. Acts as an important regulator of innate immune signaling via regulation of Toll-like receptors (TLRs), Nodlike receptors (NLRs) and RIG-I like receptors (RLRs), collectively referred to as pattern recognition receptors (PRRs). Protects cells from spontaneous formation of the ripoptosome, a large multi-protein complex that has the capability to kill cancer cells in a caspase-dependent and caspase-independent manner. Suppresses ripoptosome formation by ubiquitinating RIPK1 and CASP8.

Activity summary

CIAP2 also called E3 ubiquitin-protein ligase and encoded by the BIRC3 gene functions to inhibit apoptosis. This protein belongs to the inhibitors of apoptosis (IAP) family and is around 69 kDa in mass. cIAP2 is widely expressed in various tissues including the epithelial and lymphoid cells. It operates mechanically by ubiquitinating substrates marking them for proteasomal degradation which is key in preventing cell death and maintaining cellular homeostasis.

Biological function summary

CIAP2 serves as a regulator in cell survival by functioning within signaling cascades. It participates in the formation of the TNF receptor complex which influences the NF-κB signaling pathway and inflammation response. By interacting with several proteins cIAP2 modulates downstream signaling effects that can influence immune responses and cellular proliferation helping cells adapt and survive stressful conditions.

Pathways

CIAP2 plays roles in both the NF-κB and the MAPK signaling pathways. Within these pathways cIAP2 interacts closely with proteins such as TRAF2 and RIP1. In the NF-κB pathway it helps in the regulation of inflammatory responses while in the MAPK pathway it contributes to cell growth and differentiation processes. These pathways highlight its function in regulating immune system responses and cell adaptability.

Associated diseases and disorders

CIAP2 maintains connections with cancer and chronic inflammation. Abnormal expression or mutations of cIAP2 can lead to tumorigenesis due to disrupted apoptotic control linking it closely to cancers like lymphomas and leukemias. Additionally cIAP2 influences inflammatory diseases like Crohn's disease through its interactions with proteins such as NOD2 which further impacts the disease pathology. Proper regulation of cIAP2 is essential in avoiding unwanted cell survival and excessive inflammation highlighting its significance in various pathological conditions.

    Immunocytochemistry/ Immunofluorescence - Anti-cIAP2 antibody (ab23423)

    ab23423 staining cIAP2 in HeLa cells treated with TMCB (TMCB, Selective CK2 inhibitor ab120289), by ICC/IF. Decrease in cIAP2 expression correlates with increased concentration of TMCB, as described in literature.
    The cells were incubated at 37°C for 10 minutes in media containing different concentrations of TMCB, Selective CK2 inhibitor ab120289 (TMCB) in DMSO, fixed with 4% formaldehyde for 10 minutes at room temperature and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab23423 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

    Functional Studies - Anti-cIAP2 antibody (ab23423)

    HeLa cells were incubated at 37°C for 24h with vehicle control (0 μM) and different concentrations of TMCB (TMCB, Selective CK2 inhibitor ab120289). Decreased expression of cIAP2 in HeLa cells correlates with an increase in TMCB concentration, as described in literature.

    Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 40μg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab23423 at 2 μg/ml and Anti-Actin antibody - Loading Control ab1801 at 2 μg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (Goat Anti-Rabbit IgG H&L (HRP) ab97051 ) at 1/10000 dilution and visualised using ECL development solution.

    ICC/IF image of ab23423 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab23423, 1μg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

    Western blot - Anti-cIAP2 antibody (ab23423)

    A doublet was observed in Daudi, Ramos and Raji whole cell lysates (lanes 1, 4 and 5). This data suggests that ab23423 might react with both cIAP1 and cIAP2 proteins. The predicted molecular weights of cIAP1 and cIAP2 are 69-kDa and 68-kDa respectively.
