We previously showed in vivo that coding-end processing is specific for each coding end, suggesting that specific motifs in a coding-end sequence influence nucleotide deletion and P-region formation. Using colony formation in soft agar as a measure of full transformation, we report here that R- cells can be transformed by v-src, although they still cannot viagra be transformed by the activated c-src527 (mutation at tyrosine 527 to phenylalanine which. Learn how you can partner with. TEDx events, find and attend local, independently organized events. We propose that each coding-end sequence dictates a unique hairpin structure, the result of a particular energy conformation between nucleotides alternative organizing the loop and the stem, and that the interplay between this structure and specific sequence motifs influences the.

Phosphorylation of the E2F-1-DP-1 heterodimer by cyclin B-dependent kinases, however, did not result in down-regulation of its DNA-binding activity, as is readily seen after phosphorylation by cyclin A-dependent kinases, suggesting that phosphorylation per se is not sufficient to regulate E2F DNA-binding activity.
