knockdown of ESYT1 (and family members ESYT2 and ESYT3) significantly decreased ANO1 current density.
Title: A novel microscopy-based assay identifies extended synaptotagmin-1 (ESYT1) as a positive regulator of anoctamin 1 traffic.
This study identified and confirmed ESYT1 protein changes within the postsynaptic density in schizophrenia.
Title: Proteomic and genomic evidence implicates the postsynaptic density in schizophrenia.
ESyt2 and ESyt3, but not ESyt1, interact with activated FGFR1.
Title: Extended Synaptotagmin Interaction with the Fibroblast Growth Factor Receptor Depends on Receptor Conformation, Not Catalytic Activity.
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.
Title: PI(4,5)P(2)-dependent and Ca(2+)-regulated ER-PM interactions mediated by the extended synaptotagmins.
E-Syt1 is a mediator of cancer cell invasion.
Title: The oncogenic lung cancer fusion kinase CD74-ROS activates a novel invasiveness pathway through E-Syt1 phosphorylation.

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.
