Anti-14-3-3 Binding Domain (phospho S) antibody (ab14127)


  • Product name
    Anti-14-3-3 Binding Domain (phospho S) antibody
  • Description
    Rabbit polyclonal to 14-3-3 Binding Domain (phospho S)
  • Host species
  • Specificity
    Ab14127 binds peptides and proteins containing a motif composed of phospho-Ser with proline at the +2 position and arginine or lysine at the -3 position. Antibody binding is phospho-specific and largely independent of other surrounding amino acids. The antibody weakly crossreacts with sequences containing phospho-Thr instead of phospho-Ser in this motif and with sequences containing phospho-Ser surrounded by Phe at the +1 position and Arg/Lys at the -3 position. No crossreactivity is observed with corresponding nonphosphorylated sequences or with other phospho-Thr/Ser/Tyr-containing motifs. By ELISA ab14127 recognizes a wide range of peptides containing the 14-3-3 binding motif and by 2D gel Western blot analysis it recognizes a large number of presumptive 14-3-3 binding proteins.

  • Relevance
    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.

Thank you for your enquiry. It is very rare that an antibody will come with its matching peptide in the same catalogue number product, we typically offer those with a different catalogue number and separate price. For ab14127 it seems we do not sell t...

Thank you for your enquiry. Your motif has a proline at +2 position, but has a serine at the -3 position instead of the required Arg/Lys. These antibodies have never been tested against your SASSApSLP motif. On the other hand, there is the stateme...
