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

Protocols

Specificity / Sensitivity

LITAF Antibody dectects endogenous levels of total human LITAF protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human LITAF protein. Antibodies were purified by peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from Hep G2, HeLa and MCF-7 cell types using LITAF Antibody.

Background

LITAF (PIG7/SIMPLE) is protein that contributes to the regulation of the inflammatory cytokine TNF-α (1-3). LITAF was identified as a transcription factor involved in LPS-induced TNF-α expression through interaction with the TNF-α promoter (1,4). The same protein, called PIG7, was independently described in a model for p53 regulation (2). A putative alternative spiced form of LITAF, named SIMPLE, encodes a protein with a unique carboxyl terminus (3). Studies on LITAF-deficient mice demonstrate that LITAF plays a significant role in the regulation of several inflammatory cytokines in response to LPS (5). The regulation of LITAF can occur through phosphorylation by p38α via the TLR pathway that leads to its nuclear translocation (5). Mutation in the LITAF/SIMPLE gene has been associated with an autosomal dominant demyelinating form of Charcot-Marie-Tooth disease (6).
