WebHerpesviral nuclear egress is a regulated process of viral capsid nucleocytoplasmic release. Due to the large capsid size, a regular transport via the nuclear pores is unfeasible, so that a multistage-regulated export pathway through the nuclear lamina and both leaflets of the nuclear membrane has evolved. This process involves regulatory proteins, which support … WebMar 27, 2024 · This effect is due to the reduced efficiency of mRNA 3′ end cleavage, and in vitro analysis reveals that PTB competes with CstF for recognition of the pA signal's pyrimidine-rich downstream sequence element. This may be analogous to its role in alternative splicing, where PTB competes with U2AF for binding to pyrimidine-rich …

WebApr 13, 2024 · Using the newly developed assay, we detect the binding of eGFP-WNT-3A to endogenous HiBiT-FZD 7 and compare it with overexpressed receptors. We show that receptor overexpression results in increased membrane dynamics, leading to an apparent decrease in binding on-rate and consequently in higher, up to 10 times, calculated K d.
