The rates of uptake of both the lipid and protein components are not matched by the rate of cel- lular metabolism of these species, resulting in the accu- mulation of both ... glycation, rather than purely the loss of the parent amino acid, which is the key factor in terms of receptor recognition [29].

... those with the C-terminal domain deleted is consistent with this (Figs 4 and 5). Hybrid proteins carrying the N-terminus of one protein and the Sm domain of the other localize according to the N-terminal ... the latter, indicating that in the absence of an N-terminal domain distinct localization is lacking. Finally, the Lsm1p Sm domain by itself (LsmDN1DCp) accumu- lat...
