Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.

Protocols

Specificity / Sensitivity

DIDO1 Antibody detects endogenous levels of DIDO1 and other isoforms including DIDO2 and DIDO3. An unknown band is detected in HepG2 cells at 35 kDa.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Thr160 of human DIDO1. Antibodies were purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from COS cells, mock transfected or transfected with a construct overexpressing human DIDO1, using DIDO1 Antibody.

Western Blotting

Western Blotting

Western blot analysis of extracts from K-562 and HepG2 cells, untreated or treated with Staurosporine #9953 (1 μM for 4 hours), using DIDO1 Antibody.

Background

The putative transcription factor DIDO1 (death inducer obliterator 1, also termed DIO-1 or DATF1) contains a pair of zinc finger motifs and is upregulated by apoptotic stimuli. DIDO1 is expressed in the developing limb and may play a role in controlling programmed cell death during development (1-3). Nuclear translocation of DIDO1 during apoptosis is associated with its apoptotic activity (2). Alternative splicing produces the DIDO-1, -2 and -3 isoforms (also termed DIO-1, -2, -3), whose targeted disruption in mice produces a phenotype similar to myelodysplastic/myeloproliferative disease (MPS/MPD) in humans (3). DIDO3, the largest of the splice variants, is associated with the centrosome and plays a role in mitotic checkpoint and chromosome stability (4).
