- Segment 1 spans hCPEB3 residues 1-100; segment 2, residues 51 – 150; segment 3, residues 101 – 200; segment 4, residues 151 – 250; segment 5, residues 201 – 300; segment 6, residues 251 350; segment 7, residues 302 – 400 and finally segment 8, which is composed of residues 352 – 450. Residues of structural or functional interest are in bold font. The putative dimethyl-Arg site (R308) is highlighted in green. The putative phosphoTyr site, Y341 plausibly recognized by STAT5B’s SH2 domain is highlighted in blue. The predicted nuclear export signal, L349-L353, is highlighted in yellow. Putative phosphorylation sites: S284, S290, S297, S298, S400, S407, S408, S411 and S412 are highlighted in red. Finally, residues belonging to the first RRM1 domain are written in italics.
