The extended synaptotagmins (E-Syt1, E-Syt2, and E-Syt3) are endoplasmic reticulum-anchored proteins. They form homo- and heteromeric complexes that mediate contacts with the plasma membrane. Such contacts are critically dependent on the presence of PI(4,5)P2 in this membrane and are additionally regulated by cytosolic Ca2+ via the Ca2+-sensing property of E-Syt1.

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.
