  • Function

    May function as an inducer of apoptosis. Interacts selectively with ASC and this complex may function as an upstream activator of NF-kappa-B signaling. Inhibits TNF-alpha induced activation and nuclear translocation of RELA/NF-KB p65. Also inhibits transcriptional activity of RELA. Activates caspase-1 in response to a number of triggers including bacterial or viral infection which leads to processing and release of IL1B and IL18.
  • Tissue specificity

    Expressed in blood leukocytes. Strongly expressed in polymorphonuclear cells and osteoblasts. Undetectable or expressed at a lower magnitude in B- and T-lymphoblasts, respectively. High level of expression detected in chondrocytes. Detected in non-keratinizing epithelia of oropharynx, esophagus and ectocervix and in the urothelial layer of the bladder.
  • Involvement in disease

    Defects in NLRP3 are the cause of familial cold autoinflammatory syndrome type 1 (FCAS1) [MIM:120100]; also known as familial cold urticaria. FCAS are rare autosomal dominant systemic inflammatory diseases characterized by episodes of rash, arthralgia, fever and conjunctivitis after generalized exposure to cold.
    Defects in NLRP3 are a cause of Muckle-Wells syndrome (MWS) [MIM:191900]; also known as urticaria-deafness-amyloidosis syndrome. MWS is a hereditary periodic fever syndrome characterized by fever, chronic recurrent urticaria, arthralgias, progressive sensorineural deafness, and reactive renal amyloidosis. The disease may be severe if generalized amyloidosis occurs.
    Defects in NLRP3 are the cause of chronic infantile neurologic cutaneous and articular syndrome (CINCA) [MIM:607115]; also known as neonatal onset multisystem inflammatory disease (NOMID). CINCA is a rare congenital inflammatory disorder characterized by a triad of neonatal onset of cutaneous symptoms, chronic meningitis and joint manifestations with recurrent fever and inflammation.
  • Sequence similarities

    Belongs to the NLRP family.
    Contains 1 DAPIN domain.
    Contains 9 LRR (leucine-rich) repeats.
    Contains 1 NACHT domain.
  • Cellular localization

Thank you for contacting us.

I suggest increasing the primary antibody concentration based on the images which show poor bands for the expected size (˜95kDa)as compared to the 70kDa non specific band. I also suggest using BSA as a blocking buffer to attempt to change the conditions for antibody binding and hopefully reduce the non specific band at 70kDa.

While neither of the bands are at the expected size of 118kDa, this expected size has been based off sequence information and may be different in experiment. I note that there are isoforms of this protein with isoform 4 having a predicted 95kDa size,http://www.uniprot.org/uniprot/Q8R4B8

As the 95kDa size is likely CIAS1 / NALP3, it seems that the primary goal should be to increase the specific signal and decrease non specific binding at the 70kDa size. If you agree, I would like to send you the positive control for this product so that you may have a known sample to compare with. Ab91525 has a recommend positive control of K562 (Human erythromyeloblastoid leukemia cell line) Whole Cell Lysate - tumor cell line;https://www.abcam.com/K562-Human-erythromyeloblastoid-leukemia-cell-line-Whole-Cell-Lysate-tumor-cell-line-ab29306.html.

We do have the immunogen peptide available for this product, ab139102. There is currently a 1-2 week lead time for this product. I will attached our immunogen blocking protocol to this email for your review.

I hope this information is helpful to you and look forward to your reply. Please do not hesitate to contact us if you need any more advice or information.
