14-3-3 protein zeta/delta is a protein that in humans is encoded by the YWHAZ gene.[1]

This gene product belongs to the 14-3-3 family of proteins which mediate signal transduction by binding to phosphoserine-containing proteins. This highly conserved protein family is found in both plants and mammals, and this protein is 99% identical to the mouse, rat and sheep orthologs. The encoded protein interacts with IRS1 protein, suggesting a role in regulating insulin sensitivity. Two transcript variants differing in the 5' UTR, but encoding the same protein, have been identified for this gene.[2]



YWHAZ has been shown to interact with TSC2,[3] LIMK1,[4] CDC25B,[5] AKT1,[6] BCAR1,[7] Interleukin-9 receptor,[8] C-Raf,[9][10][11][12][13] HMGN1,[14] Vimentin,[10] Tau protein,[15] Protein kinase Mζ,[16][12] GP1BB,[17][18][19] GP1BA,[17][20][19] TNFAIP3,[21][22] Bcl-2-associated death promoter,[23] PRKCE[24] and P53.[25]
