Anti-SET-beta, clone 3D10E2

Protein SET (UniProt Q01105; also known as HLA-DR-associated protein II, IGAAD, Inhibitor of granzyme A-activated DNase, PHAPII, I-2PP2A, Phosphatase 2A inhibitor I2PP2A, TAF-I, Template-activating factor I) is encoded by the SET gene (Gene ID 6418) in human. Protein SET (patient “SE translocation”) adopted its name when it was originally identified in a leukemia study in 1992. SET interacts with signaling pathways that promote normal cell growth and proliferation, as well as tumorigenesis and metastasis. SET protein inhibits PP2A by enhancing lyase activity of P450c17, a substrate for PP2A when it is Ser- and Thr-phosphorylated. Alternative splicings result in multiple SET isoforms, including SET-alpha (TAF-I alpha), SET-beta (TAF-I beta), and a shorter spliced Set-β isoform without the nuclear localization signal (NLS). Set-β functions have been described both in the nucleus and cytoplasm. The presence of a nuclear localization signal (NLS) and phosphorylation govern Set-β isoforms cellular localization. Proteolytic cleavage of Set-β at Lys176 by granzyme A or at Asn-175 by asparagine endopeptidase results in the release of GzmA-activated DNase (GAAD) from a multiprotein complex. Uninhibited in the absence of the full-length Set-β, GAAD causes cell death by its DNA-nicking activity.

Clone 3D10E2 recognizes an epitope sequence specific to the spliced isoform SET-beta (TAF-I beta) of human, murine, and rat species (UniProt Q01105-2, Q9EQU5-2, Q63945-2). The epitope sequence is not present in SET-alpha (TAF-I alpha) or any other human, murine, and rat protein SET spliced isoforms reported by UniProt.

Epitope: Near N-terminus.

KLH-conjugated linear peptide corresponding to a sequence near the N-terminus of human SET-beta.

Evaluated by Western Blotting in DU145 cell lysate.

Western Blotting Analysis: 0.5 µg/mL of this antibody detected SET-beta in 10 µg of DU145 human prostate cancer cell lysate.

~36 kDa observed. Band size appears larger than the calculated molecular weight of 31.97 kDa (Met1 removed) due to posttranslational modification (acetylation and/or phosphorylation).
