  • Function

    Probable kinase that may be involved in a calcium-signaling pathway controlling neuronal migration in the developing brain. May also participate in functions of the mature nervous system.
  • Tissue specificity

    In fetal tissues, highly expressed in brain, detectable in lung and liver, but not in kidney. In adult tissues, expressed ubiquitously in the brain, detectable in the heart, liver, spleen, thymus, prostate, testis, ovary, small intestine and colon. The type A isoforms seem to be expressed predominantly in fetal brain whereas type B isoforms are expressed abundantly in both fetal and adult brain.
  • Sequence similarities

    Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily.
    Contains 2 doublecortin domains.
    Contains 1 protein kinase domain.

  • ab31704 at a 1/1000 dilution staining DCAMKL1 in rat brain tissue sections (hippocampus) by Immunohistochemistry/ PFA perfused, frozen sections, incubated for 18 hours at 20°C in PBS + 0.3% Triton X-100. Secondary used at 1/1000 polyclonal Goat anti-rabbit conjugated to Alexa Fluor 488.
    The immunostaining was performed using the `free floating` technique, using direct fluorescence. The antibody beautifully stains tracts of fibers in many brain areas such as the cortex, striatum. The image shown is staining observed at the level of the striatum.

  • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
    Lane 2: DCAMKL1 knockout HAP1 whole cell lysate (20 µg)
    Lane 3: NIH3T3 whole cell lysate (20 µg)
    Lane 4: Human brain whole tissue lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab31704 observed at 90 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab31704 was shown to specifically react with DCAMKL1 in wild-type HAP1 cells along with additional cross reactive bands. No bands were observed when DCAMKL1 knockout cells were examined. Wild-type and DCAMKL1 knockout samples were subjected to SDS-PAGE. ab31704 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1 µg/ml and 1/10,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

  • ab31704 stained in PC12 cells. Cells were fixed with 100% methanol (5 min) at room temperature and incubated with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% Tween for 1h at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab31704 at 5µg/ml and ab7291 (Mouse monoclonal to alpha Tubulin - Loading Control) used at a 1/1000 dilution overnight at +4°C. The secondary antibodies were ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed, (pseudo-colored green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594) preadsorbed, (colored red), both used at a 1/1000 dilution for 1 hour at room temperature. DAPI was used to stain the cell nuclei (colored blue) at a concentration of 1.43 µM for 1hour at room temperature.

  • DCAMKL1 was immunoprecipitated using 0.5mg Mouse Brain whole tissue lysate, 5µg of Rabbit polyclonal to DCAMKL1 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, Mouse Brain whole tissue lysate 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 ab31704.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 82kDa: DCAMKL1; non specific - 52 and 27kDa: We are unsure as to the identity of this extra band.
  • Anti-DCAMKL1 antibody (ab31704) at 1 µg/ml + Mouse Brain Whole Tissue Lysate at 20 µg

    IR Dye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/15000 dilution

    Performed under reducing conditions.

    Predicted band size: 47, 82 kDa
    Observed band size: 47,82 kDa
    why is the actual band size different from the predicted?

    The 82 kDa and 47 kDa bands correspond to the AL and BL isoforms respectively. This antibody should not detect the AS and BS isoforms of DCAMLK1.
  • ICC/IF image of ab31704 stained PC12 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab31704, 1µg/ml) overnight at +4°C. 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) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue).

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Performed under reducing conditions.

    Predicted band size: 47, 82 kDa
    Observed band size: 47,82 kDa why is the actual band size different from the predicted?
    Additional bands at: 30 kDa, 52 kDa (possible post-translational modification), 54 kDa (possible post-translational modification). We are unsure as to the identity of these extra bands.

    Exposure time: 5 minutes

    The 82 kDa and 47 kDa bands correspond to the AL and BL isoforms respectively. DCAMLK1 has a number of potential phosphorylation sites which may explain the higher migrating bands at 52 and 54 kDa.
