The proteins that are directly involved in PTMs of histones can be divided into three categories: the enzymes that create these modifications (the "writers"), the proteins that recognize the modifications (the "readers"), and the enzymes that remove the modifications (the "erasers").
In 2007, we introduced the use of small peptide loops that, upon binding of the hapten, specifically recognize the modifications of the antigen-binding site on the antibody, and therefore can be used to detect the formation of the immunocomplex (IC).
It can be explained that, actually, when n is too large, the enhancement influence on the output image is too slight, that is, it is difficult to recognize the modification in the overall brightness.
However, some regions in the enhanced image of the BPDHE method are dimmed unexpectedly with medium brightness pixels, while an enhancement of the RSWHE method is not strong enough to recognize the modification in the contrast.
Notably, the brain form of α-dystroglycan has a higher affinity for laminin-511/521 than its muscle counterpart, and the brain-specific mAb is thought to recognize the modification that binds to the LG domains of the laminin α5 chain.
In their excellent paper, Deadman and Kelly 1978 note that the students in their study rarely recognized the significance of slight modifications and their adaptive value.
We have recognized the association of different epigenetic modifications with gene expression, but the triggers for the differential marking of epigenetic modifications throughout the genome is largely unclear.
In this study, Tyr391 phosphorylation of human K19 was demonstrated by the use of a phospho-specific antibody recognizing the specific modification in PV-treated cells and mice.
A second enzyme, Lsp (lipotein signal peptidase), recognizes the diacylglyceryl modification and cleaves the leader sequence, when lipoproteins are translocated through the cytoplasmic membrane [63], resulting in the mature lipoprotein.
Many so-called specific phosphotyrosine antibodies actually recognize the phosphotyrosine modification independently of its sequence context.
An antibody that recognizes the Q209E modification of Gαq was a gift of Prof. S. Kamitami (Osaka, Japan).
