... and since one of the major foci of the study was to try to find general means of deciding attachment of PPs, individualization of these PPs was, at first, discounted. In some of the prior ... and locative indicators. Of the remaining PPs, 189 (60% of the remaining) were temporal, 90 (28%) were locative, and 34 (12%) were of a mixed variety. Some examples of these are...

We also show that tau interacts with the SH2 domain of Fyn, and that this associa- tion, unlike that of Fyn-SH3, is influenced by Fyn-mediated tyrosine phos- phorylation of ... SH3 domain of Fyn binds to proline-rich motifs within the sequence PXXP in interacting pro- teins. Seven such motifs are present in the proline-rich domain of the longest isoform of ta...
