Target
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, TRAF2, DIABLO/SMAC, MAP3K14/NIK, MAP3K5/ASK1, IKBKG/NEMO, IKBKE and MXD1/MAD1. Can also function as an E3 ubiquitin-protein ligase of the NEDD8 conjugation pathway, targeting effector caspases for neddylation and inactivation. 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. Can stimulate the transcriptional activity of E2F1. Plays a role in the modulation of the cell cycle.

Sandwich ELISA analysis of human cIAP1 matched pair antibodies
Capture: HA723280, cIAP1 Rabbit mAb [PSH06-72] Detector: HA723282, cIAP1 Rabbit mAb [PSH06-71]
Elisa assay was performed by coating wells of a 96-well plate with 50 µl per well of capture antibody (HA723280) diluted in carbonate/bicarbonate buffer, at a concentration of 2 µg/ml overnight at 4℃. Wells of the plate were washed, blocked with 150 µl 0.05% tween-20 1% BSA blocking buffer, and incubated with serial diluted Recombinant Human cIAP1 protein (HA211301) starting from 8,000 pg/ml to 0 pg/ml and detect antibody (HA723282, Biotin, 0.2 µg/ml) for 1 hour at 30℃ with shaking. Then the plate was washed and incubated with 50 µl per well of SA-HRP for 0.5 hour at 30℃ with shaking. Detection was performed using an Ultra TMB Substrate for 10 minutes at room temperature in the dark. The reaction was stopped with sulfuric acid and absorbances were read on a spectrophotometer at 450 nm.

Interpolated concentrations of native cIAP1 in THP-1 and TF-1 extract samples based on a 1,000 µg/ml extract load.
Capture: HA723280, cIAP1 Rabbit mAb [PSH06-72] Detector: HA723282, cIAP1 Rabbit mAb [PSH06-71]
The concentrations of cIAP1 were measured in duplicates, interpolated from the cIAP1 standard curve and corrected for sample dilution. Undiluted samples are THP-1 extract 25% and TF-1 extract 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean cIAP1 concentration was determined to be 1,712 pg/ml in THP-1 extract and 1,800 pg/ml in TF-1 extract.
