The best antibodies to detect FOX transcription factors

16/10/2014 by Philippe Fixe, PhD No Comments
FOX & FOX (Forkhead box) transcription factors antibodies

FOX transcription factor family members regulate the expression of genes known to play a critical role in embryonic development and organ morphogenesis. These “helix-turn-helix” class of proteins display a common “forkhead” motif and are encoded by Forkhead genes. Recent lines of evidences suggest that FOX proteins are promising therapeutical targets and biomarkers in various areas. A good opportunity to review of the most reliable FOX primary antibodies for research applications!

Citrullination: Taking the Charge out of Arg

by Ali El Baya, PhD No Comments

Protein citrullination (a.k.a. deimination) is a novel arginine-directed post-translational modification (PTM) that results in a permanent change in the targeted protein. PeptidylArginine Deiminases (PADs) mediate the calcium-dependent deimination of the guanidino group of Arginine side chains to form an ureido group and the non-standard amino acid citrulline.

Some biologically relevant proteins known to be citrullinated include Keratin, Filaggrin, Trichohyalin, Vimentin, Myelin Basic Protein (MBP), Histones, alpha-Enolase, Fibrinogen, Fibrins, Collagen type I and II, beta-Actin, and Tubulin 9-11… It is noteworthy that several of these proteins are part of the cytoskeleton and/or are structural in nature.

Citrullination

Citrullination of peptidyl-arginine by peptidylarginine deiminases (PADs).

In their October newsletter, Cytoskeleton Inc. presents an overview about the consequences of citrullination, especially referring to cytoskeleton proteins such as Vimentin.
