Optimal dilutions/concentrations should be determined by the end user.
FunctionAdapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.
Sequence similaritiesBelongs to the 14-3-3 family.
modificationsThe delta, brain-specific form differs from the zeta form in being phosphorylated (By similarity). Phosphorylation on Ser-184 by MAPK8; promotes dissociation of BAX and translocation of BAX to mitochondria. Phosphorylation on Ser-58 by PKA; disrupts homodimerization and heterodimerization with YHAE and TP53. This phosphorylation appears to be activated by sphingosine. Phosphorylation on Thr-232; inhibits binding of RAF1.
Cellular localizationCytoplasm. Melanosome. Located to stage I to stage IV melanosomes.

ab51129 staining 14-3-3 zeta in Human glioblastoma samples (A) and low grade tumors (B) by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/50) overnight. Nuclei stained blue with hematoxylin. Scale bars = 20 µm
This image shows paraffin-embedded human breast carcinoma tissue stained with ab51129 at a dilution of 1/100. Right hand image: tissue treated with immunising peptide; left hand image: untreated tissue
ICC/IF image of ab51129 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab51129, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
