Target

  • Function

    Has a role in both cell adhesion by acting as an adhesion receptor for THBS1 on platelets, and in the modulation of integrins. Plays an important role in memory formation and synaptic plasticity in the hippocampus (By similarity). Receptor for SIRPA, binding to which prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. Interaction with SIRPG mediates cell-cell adhesion, enhances superantigen-dependent T-cell-mediated proliferation and costimulates T-cell activation. May play a role in membrane transport and/or integrin dependent signal transduction. May prevent premature elimination of red blood cells. May be involved in membrane permeability changes induced following virus infection.
  • Tissue specificity

    Very broadly distributed on normal adult tissues, as well as ovarian tumors, being especially abundant in some epithelia and the brain.
  • Sequence similarities

    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Cellular localization

    Cell membrane.

    Exposure time: Lane 1: 26 seconds; Lane 2: 70 seconds; Lanes 3-4: 3 minutes; Lane 5: 3 seconds.

    Blocking/Dilution buffer: 5% NFDM/TBST.

    We recommend that samples are not boiled after adding loading buffer as this may cause protein aggregates. The molecular mass observed is consistent with the literature (PMID 12393467, PMID 11034562).
