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

Protocols

Specificity / Sensitivity

Deltex-2 Antibody detects transfected levels of total Deltex-2 protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala607 of human Deltex-2. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from COS cells, untransfected or transfected with mouse Deltex-2, using Deltex-2 Antibody.

Background

Deltex (DTX) encodes a putative E3 ubiquitin ligase first identified from Drosophila and shown to modulate Notch signaling (1). Several mammalian Deltex homologs have been isolated (2,3), all containing a pair of WWE repeats, a proline-rich region, and a Ring-finger domain (4,5). Deltex binds to the ankyrin-repeat domain of Notch and is capable of regulating Notch signaling positively or negatively in different systems (4,6). In addition, Deltex can also form homo-multimers (4). While Deltex has been implicated in Notch signaling regulation of lymphocyte development, this signal modifier may also have a transcriptional function independent of Notch (3, 6-8).
