Extracellular recordings revealed that the V337M tau mutation leads to an abnormal increase in neuronal activity in response to chronic depolarization. In neurons with this mutation, axon initial segment (AIS) plasticity is impaired by the abnormal accumulation of end-binding protein 3 (EB3) in the AIS submembrane region.

IP3K-A binds to EB3 and their binding affinity is precisely regulated by protein kinase A (PKA)-dependent phosphorylation of IP3K-A at Ser119 (pSer119). The complex of IP3K-A and EB3 dissociates and reassociates rapidly during chemically induced LTP.
Title: PKA-dependent phosphorylation of IP3K-A at Ser119 regulates a binding affinity with EB3.
One candidate pathway coupling actin filaments to microtubules consists of the actin filament-binding protein drebrin and the microtubule-binding +TIP protein EB3. This pathway is regulated proximally by cyclin-dependent kinase 5 phosphorylation of drebrin but the upstream elements in the pathway have yet to be identified.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
