  • FunctionSeems to play a role in the formation of functional distinct domains critical for saltatory conduction of nerve impulses in myelinated nerve fibers. Seems to demarcate the paranodal region of the axo-glial junction. In association with contactin may have a role in the signaling between axons and myelinating glial cells.
  • Tissue specificityPredominantly expressed in brain. Weak expression detected in ovary, pancreas, colon, lung, heart, intestine and testis.
  • Sequence similaritiesBelongs to the neurexin family.
    Contains 2 EGF-like domains.
    Contains 1 F5/8 type C domain.
    Contains 1 fibrinogen C-terminal domain.
    Contains 4 laminin G-like domains.

  • Overlay histogram showing SH-SY5Y cells stained with ab105571 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab105571, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
