Target

  • Function

    V-SNARE that mediates vesicle transport pathways through interactions with t-SNAREs on the target membrane. These interactions are proposed to mediate aspects of the specificity of vesicle trafficking and to promote fusion of the lipid bilayers. May be concerned with increased secretion of cytokines associated with cellular senescence.

  • Tissue specificity

    Expressed in all tissues examined.

  • Sequence similarities

    Belongs to the VTI1 family.

  • Cellular localization

    Endomembrane system. Cytoplasmic granule.
  • Information by UniProt

     ab184170 Anti-VTI1B antibody [EPR15506(B)]  was shown to specifically react with VTI1B in wild-type HeLa cells. Loss of signal was observed when knockout cell line ab265483 (knockout cell lysate ab257797) was used.  Wild-type and VTI1B knockout samples were subjected to SDS-PAGE.  ab184170 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively.  Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
