Annotation description:Fig.1: "Immunolocalization of polyadenylation/translation factors in dendrites of cultured hippocampal neurons"
- "Cultures of rat primary hippocampal neurons were probed with antibodies directed against PAP, the 100 kDa subunit of CPSF (CPSF100), Aurora, maskin and eIF4E (all of the antibodies have been used previously for immunolocalization; Hodgman et al., 2001), as well as those against synaptophysin and αCaMKII, which serve as synaptic markers. Figure 1A shows that immunoreactivity for all these polyadenylation/translation factors was evident in the cell body, and in some cases was distributed as puncta along the dendrites, which is similar to that observed for CPEB (Wu et al., 1998). "

Fig.2: "Identification of polyadenylation/translation factors at the postsynaptic density (PSD)"
- " All the other polyadenylation/translation factors were detected in the PSD, although only Aurora and maskin were enriched in that fraction (Figure 2A). Because PAP, CPSF100 and eIF4E are known to function in other regions of neurons, their lack of enrichment in the PSD was an expected result."
