14-3-3 Family

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** The 14-3-3 family of proteins mediates signal transduction by binding to phosphoserine-containing proteins. Two different binding motifs, RSXpSXP and RXY/FXpSXP, are present in nearly all known 14-3-3 binding proteins. The 14-3-3 dimer binds tightly to single molecules containing tandem repeats of phosphoserine motifs, implicating bidentate association as a signaling mechanism with molecules such as Raf, BAD, and Cbl.
