DNA-binding factors of B lymphoid cells are susceptible to limited proteolytic cleavage during nuclear extract preparation.
DNA-binding proteins that interact with the 3' end of the mouse mu immunoglobulin heavy chain gene were identified by the electrophoretic mobility shift assay. Complexes of distinctly different mobilities were formed by extracts prepared from B lymphoid lines representing different stages of maturation. The apparent stage-specific differences are shown to be due to proteolytic events that occur...
متن کاملFactor B Binding to Lymphoid Cells
A receptor for fluid phase human complement (C) components C3 and C3b (1, 2) was found on the surface membranes of human lymphoblastoid cells. No other C proteins or serum factors were needed to mediate binding of C3 or C3b to this receptor. In studying its biological importance, we demonstrated that Raji cells cultured in medium containing fresh normal human serum (NHS) 1 and cobra venom facto...

متن کاملVascular endothelial cell proteoglycans are susceptible to cleavage by neutrophils.
Heparan sulfate proteoglycan associated with vascular endothelial cells in vivo plays an important role in a number of endothelial functions, including the inhibition of intravascular coagulation and extravasation of plasma proteins and blood cells. In this report, we demonstrate that polymorphonuclear neutrophils, as well as cell-free neutrophil supernatants, lead to a rapid and dramatic loss ...
متن کاملDuring its nuclear phase the multifunctional regulatory protein ICP0 undergoes proteolytic cleavage characteristic of polyproteins.
ICP0 is a multifunctional herpes simplex virus protein known primarily as a promiscuous transactivator. In the course of productive infection, it is localized during the first 5-7 h in the nucleus and later in the cytoplasm. In the nucleus, its primary activities are to suppress the silencing of viral DNA by host proteins, activate cdk4 through recruitment of cyclin D3 to the sites of formation...
