Immunoblots identifying 14-3-3 isoforms in extracts from mouse oocytes, eggs and ovaries. Proteins from cell lysates were separated by electrophoresis under reducing conditions, transferred to membranes and probed with antibodies directed against the 14-3-3 isoforms indicated. Each isoform shown was detected in lysates of 200 oocytes or 200 eggs. Protein extracts of ovaries and brain from adult mice are included for comparison. The 14-3-3 protein is approximately 30 kDa.

(K, L) 14-3-3σ. (M, N) 14-3-3η. Confocal sections with regions of red fluorescence indicating the corresponding isoforms studied (see Methods). The inset in N shows the same egg labeled blue with Hoechst DNA stain (non-confocal image) and confirms that the darker areas in this region of the larger image are condensed metaphase II chromosomes. Control cells were included for each isoform experiment and were imaged using the same confocal settings. Representative control oocytes and eggs are shown in bright-field (O) and fluorescence (P). 14-3-3η accumulates, in part, in the meiotic spindle in eggs as shown by simultaneous labeling with 14-3-3η (Q) and tubulin (R) antibodies. These sequential scans are merged (14-3-3η + tubulin) in (S). The scale bars represent 10 µm for all images.

Representative immunocytochemistry images of 14-3-3 protein isoforms along and in the zonae pellucidae of cumulus-free oocytes isolated from ovaries of adult mice. The zona-intact cells were fixed in paraformaldehyde but not treated with detergent (see Methods). Paired images of an oocyte (left image is brightfield and right is immunofluorescence) indicate staining along the zona and/or the cell membrane for all isoforms except 14-3-3ζ. Note: the intent of this part of the study was not to examine the intracellular distribution of the isoforms (see Figure 3 for those experiments) since the cells were not permeabilized to permit complete antibody penetration; however, cells may be partially permeabilized by fixation accounting for the detection of intracellular proteins in some cells.

    • Rabbit anti 14-3-3 τ/θ antibody recognizes 14-3-3 tau/theta in all mammals. It is a member of the 14-3-3 family which consists of 30 kDa proteins involved in multiple cell signalling pathways, regulation of cell cycle progression, cytoskeletal structure, transcription, intracellular trafficking and targeting. Protein interactions with 14-3-3 show distinct preferences for it’s different isoforms and are regulated by phosphorylation of both 14-3-3 and the bound protein.

      14-3-3 tau/theta is primarily expressed in T-cells although it occurs at lower levels in the brain, heart, pancreas placenta and kidneys. It plays a role in cell cycle progression via interaction with p27(Kip1). Along with COPI, the theta isoform binds the GB1 RSR sequence involved in protein trafficking. The isoform forms a complex with Hsp60 and cellular prion protein which may be involved in prion diseases. Elevated levels of 14-3-3 tau/theta are observed in amyotrophic lateral sclerosis. 14-3-3 tau/theta also binds BCR/Abl, bacterial effector protein Tir, yes-associated protein and the FSH receptor.

      Rabbit anti 14-3-3 τ/θ antibody may not react with recombinant proteins that are not N-acetylated.
