EDC4/Ge-1 Antibody #2548
|W IP IF-IC||H M Mk||Endogenous||170||Rabbit|
Reactivity Key: H=Human M=Mouse Mk=Monkey
Species cross-reactivity is determined by western blot. Species enclosed in parentheses are predicted to react based on 100% sequence homology.
Specificity / Sensitivity
EDC4/Ge-1 Antibody detects endogenous levels of total EDC4/Ge-1 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human EDC4/Ge-1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from 293 and Hep G2 cells using EDC4/Ge-1 Antibody.
Enhancer of mRNA decapping 4 (EDC4) was originally identified as the autoantigen Ge-1 from a Sjögren's syndrome patient later diagnosed with primary biliary cirrhosis (1). EDC4 (also known as HEDLS) was later identified as an essential component of cytoplasmic P-bodies responsible for mRNA decapping and degradation (2). Identified EDC4 protein is found as a pair of isoforms generated by alternative splicing and contains several WD domains and a putative nuclear localization signal. EDC4 co-localizes with other P-body decapping proteins such as DCP1A, DCP2 and GW182 (2,3). Experimental evidence suggests that EDC4 may be involved in miRNA-mediated translation repression (4).
