The 14-3-3 proteins are a highly conserved family of proteins involved in the regulation of cell survival, apoptosis, proliferation and checkpoint control.
Biological regulation by 14-3-3 is mediated through phosphorylation-dependent protein-protein interactions.
Two different phospho-Ser-containing motifs are found within nearly all known 14-3-3 binding proteins.
Motif 1 (Arg/Lys and Ser at positions -3 and -2, phospho-Ser at position 0, and Pro at position +2) is found in critical regulatory proteins including Bad, cdc25c, FKHRL1, PKC and c-Raf.
This antibody provides a powerful tool for the discovery and characterization of potential 14-3-3 binding proteins containing this motif and for high throughout drug discovery.

仕様
Size：100ul
Host：rabbit
Grade：Affinity Purified
Purity：Purified by Protein A and peptide affinity chromatography.
Form：Supplied as a liquid in 10mM sodium HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol.
Specificity：Recognizes peptides and proteins containing a motif composed of phospho-Ser with proline at the +2 position and arginine or lysine at the -3 position. Phospho-specific and largely independent of other surrounding amino acids. Weak crossreactivity with sequences containing phospho-Thr instead of phospho-Ser in this motif; with sequences containing phospho-Ser surrounded by Phe at the +1 position; with Arg/Lys at the -3 position. No crossreactivity observed with corresponding non-phosphorylated sequences or with other phospho- Thr/Ser/Tyr -containing motifs.
