Using standard binding assays with radiolabeled ligand and COS-7 cells, substitutions in the dileucine motif or deletion of tyrosine residues in the G-CSFR did not alter internalization.
This work studies the possibility of using electrodeposited polypyrrole as an oxygen reducing electrocatalyst in photoactivated fuel cells by substitution of the standard Pt/Carbon-Black electrocatalyst.
In zebrafish cells, the substitution of Ser-270 for alanine blocked the phosphorylation and activation of nSMase1, whereas the substitution of Ser-270 for negatively charged glutamic acid mimicked the effect of phosphorylation.
In 3201 cells, alanine substitutions introduced into residues S392 and S393 did not significantly affect the binding of SU mutants to CXCR4, whereas introduction of methionine (S392M or S393M) dramatically reduced CXCR4 binding.
In healthy cells, base substitutions occur at an extremely low incidence during both DNA replication [ 2] and RNA synthesis [ 3].
A carbon based nanocatalyst in the form of graphene hybridized MoNiCoS (MoNiCoS /Go) was synthesized in a single step hydrothermal method for methanol oxidation in a direct methanol fuel cell, as a substitution for expensive and rare platinum.
The results indicated that the Ca, as a single dopant, caused obvious shrinkage of the 2 14:1 phase crystal cell, indicating the substitution of Ca for the rare earth elements, since the Ca metallic radius is much larger than the value for Fe [23].
The results indicate that the volume of poplar wood treated by MAN swells about 9% with about 15% of weight percent gain, and MAN chemically bonds to the cell wall through substitution reaction with hydroxyl group, and the grafting adduct mainly remains as an amorphous form.
An amyloid-forming homologous peptide rescued aggregation and biofilm activity of Als5pV326N cells, and V326N substitution peptide inhibited aggregation and biofilm activity in Als5pWT cells.
Faster internalization of the virus into cells after N194K substitution might suggest that this region has some role in host cell binding.
