Subcellular location [CC][Cyclin-dependent kinase 5 activator 1, p35]: Cell membrane {ECO:0000305|PubMed:17671990};
Lipid-anchor {ECO:0000269|PubMed:18507738};
Cytoplasmic side {ECO:0000305}. Cell projection, neuron projection {ECO:0000269|PubMed:10604467}. Note=In the primary cortical neurons, p35 is present in the peripheries and nerve terminals. {ECO:0000269|PubMed:10604467}.;
[Cyclin-dependent kinase 5 activator 1, p25]: Nucleus {ECO:0000269|PubMed:18507738}. Cytoplasm, perinuclear region {ECO:0000269|PubMed:10604467}. Perikaryon {ECO:0000269|PubMed:10604467}. Note=The conversion of p35 to p25 relocalizes the protein from the cell periphery to the cytoplasm, in nuclear and perinuclear regions (PubMed:18507738). In the primary cortical neurons, p25 is primarily concentrated in the cell soma and is largely absent from neurites (PubMed:18507738). {ECO:0000269|PubMed:18507738}.
