Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting,

Specificity / Sensitivity

Phospho-Thr-Pro-Pro Motif [pTPP] (D61C3) Rabbit mAb recognizes endogenous levels of proteins only when phosphorylated within the TPP motif. It does not cross react with phospho-serine or phospho-threonine in other contexts.

Source / Purification

Monoclonal antibody is produced by immunizing animals with synthetic peptide library containing the phospho-Thr-Pro-Pro motif.

Western Blotting

Western Blotting

Western blot analysis of extracts from HCT 116 cells, G0 cells that were serum starved and contact inhibited (36 hr) or mitotic cells treated with thymidine (2 mM, 18 hr) followed by Nocodazole #2190 (50 ng/ml, 20 hr), using Phospho-Thr-Pro-Pro Motif [pTPP] (D61C3) Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower).


The phospho-Thr-Pro-Pro motif is a subgroup of the phospho-Thr-Pro motif that is phosphorylated by proline-directed protein kinases, including MAP kinases and cyclin dependent kinases (CDKs). Proline-directed phosphorylation is one of the major regulatory phosphorylation events in cell proliferation, cell differentiation, and a number of other essential cellular processes (1-6). This motif was identified in both phospho-proteomic and motif X analyses as a significant phospho-thr motif (7,8).
