  • Function
    Inositol 5-phosphatase which has a role in clathrin-mediated endocytosis.
  • Tissue specificity
    Concentrated at clathrin-coated endocytic intermediates in nerve terminals. Isoform 1 is more enriched than isoform 2 in developing brain as well as non-neuronal cells. Isoform 2 is very abundant in nerve terminals.
  • Sequence similarities
    Belongs to the synaptojanin family.
    In the central section; belongs to the inositol-1,4,5-trisphosphate 5-phosphatase family.
    Contains 1 RRM (RNA recognition motif) domain.
    Contains 1 SAC domain.
  • Domain
    Binds to EPS15 (a clathrin coat-associated protein) via a C-terminal domain containing three Asn-Pro-Phe (NPF) repeats.
    The C-terminal proline-rich region mediates binding to a variety of SH3 domain-containing proteins including AMPH, SH3GL1, SH3GL2, SH3GL3 and GRB2.

  • All lanes : Anti-Synaptojanin antibody - Synaptic Marker (ab19904) at 1 µg/ml

    Lane 1 : Rat Brain lysate
    Lane 2 : Rat Brain lysate with Rat Synaptojanin peptide (ab20433) at 1 µg/ml

    Lysates/proteins at 20 µg per lane.

    All lanes : Alexa Fluor Rabbit polyclonal to Goat IgG at 1/5000 dilution

    Performed under reducing conditions.

    Predicted band size: 150 kDa
    Observed band size: 150 kDa

    ab19904 detected the expected 150kDa band in non-boiled (rat brain lysate) sample only and the detection of this band was blocked by addition of immunising peptide ab20433
  • ICC/IF image of ab19904 stained rat PC12 cells. The cells were methanol fixed (5 min), permabilised in PBS-T (20 min) and incubated with the antibody (ab19904, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

  • Immunohistochemistical detection of Synaptojanin using ab19904 on mouse brain PFA perfusion-fixed sections. Primary antibody ab19904 diluted at 1/300 and incubated for 18 hours @ 20°C in PBS + 0.3 % Triton X100. Secondary antibody: goat anti-rabbit Alexa Fluor 488® (1/1000). Image: immunostaining obtained in the mouse hippocampus on perfusion-fixed free floating sections using ab19904 at 1/300 using direct fluorescence. The staining is so strong that it is hard to determine the cellular localisation, but it seems to be cytoplasmic.

  • Immunohistochemical analysis of PFA-perfusion fixed mouse brain tissue, staining Synaptojanin with ab19904.

    Tissue was post-fixed in 4% paraformaldehyde overnight at 4°C. Sections were incubated in a blocking buffer of 0.3% Triton-X-100, 1% BSA and 10% NGS in PBS for 2 hours at room temperature, before incubating with primary antibody (1/100) for 2 days at 4°C. An AlexaFluor®-conjugated anti-rabbit IgG (1/1000) was used as the secondary antibody.
  • Synaptojanin was immunoprecipitated using 0.5mg Rat brain tissue, 5µg of Rabbit polyclonal to Synaptojanin and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Rat brain tissue lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab19904.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 150kDa; Synaptojanin
