  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function
      Apoptotic suppressor. The BIR motifs region interacts with TNF receptor associated factors 1 and 2 (TRAF1 and TRAF2) to form an heteromeric complex, which is then recruited to the tumor necrosis factor receptor 2 (TNFR2).
    • Tissue specificity
      Highly expressed in fetal lung, and kidney. In the adult, expression is mainly seen in lymphoid tissues, including spleen, thymus and peripheral blood lymphocytes.
    • Involvement in disease
      Note=A chromosomal aberration involving BIRC3 is recurrent in low-grade mucosa-associated lymphoid tissue (MALT lymphoma). Translocation t(11;18)(q21;q21) with MALT1. This translocation is found in approximately 50% of cytogenetically abnormal low-grade MALT lymphoma.
    • Sequence similarities
      Belongs to the IAP family.
      Contains 3 BIR repeats.
      Contains 1 CARD domain.
      Contains 1 RING-type zinc finger.

    • Anti-cIAP2 antibody [E40] (ab32059) at 1/1000 dilution + Daudi cell lysate.

      Predicted band size: 72 kDa
      Observed band size: 72 kDa

    • ab32059 at a 1:50 dilution staining cIAP2 in human normal spleen, using Immunohistochemistry, Paraffin Embedded Tissue.
    • cIAP2 was immunoprecipitated using 0.5mg Daudi whole cell extract, 5µg of Rabbit polyclonal to cIAP2 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
      The antibody was incubated under agitation with Protein G beads for 10min, Daudi whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
      Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab32059.
      Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
      Band: 72kDa; cIAP2
