There was colocalization of Kv2.1 and Kv2.2 with endogenous VAPA at ER-PM junctions in mouse brain neurons. Expression of Kv2.1 recruits VAPA to ER-PM junctions. Knocking out VAPA expression disrupts Kv2.1 clustering.The domains of VAPs and Kv2.1 necessary and sufficient for their association at ER-PM junctions were 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.
