In contrast, exposure to NHS biotin, which efficiently modifies lysine residues and disrupts the DNA-binding activity of many proteins, resulted in a nearly complete loss of XPA's DNA-binding affinity.
Many black dots of different intensities were detected in the grid, supporting a histone binding activity of BAHBAHD1.
Furthermore, the DNA binding activity of c-Myb was studied.
The erythrocyte binding activity of rPfRH240 was also studied in similar erythrocyte binding assays.
Binding activity of dust samples.
Also, pifithrin- α is a potent agonist of p53, which can decrease both the nuclear stability and the basal DNA-binding activity of p53 in many cells (Komarov et al, 1999; Murphy et al, 2004; Sohn et al, 2009).
Alternative splicing mechanism has been indicated to subtly regulate the ligand binding and signalling activity of many integrin subunits (reviewed in [ 34]).
Importantly, an accessory protein, proliferating cell nuclear antigen (PCNA), has been implicated in binding and coordinating the activity of many LP-BER enzymes.
For loading controls, the nuclear extracts were analysed also for the DNA-binding activity of octamer-1 (Oct-1), whose site is present in many housekeeping genes [57].
Moreover, this variant of immobilization of SPA improves the IgG-binding activity of SPA as well as further antigen-binding activity of antibody molecules immobilized through SPA [24].
The Groucho/TLE (transducin-like enhancer) family of co-repressor proteins also regulate development and modulate the activity of many DNA-binding transcription factors during a range of diverse cellular processes including haematopoiesis.
