  • Function

    Plays an important role in integrin-mediated signaling and functions both in regulating cell migration and immune responses. Promotes formation of focal adhesion complexes, activation of the protein kinase PTK2/FAK1 and subsequent phosphorylation of MAPK1 and MAPK3. Promotes production of proinflammatory cytokines by monocytes and macrophages. Plays an important role in modulating inflammation and T-cell-mediated immune responses. Promotes axon growth in the embryonic olfactory bulb. Promotes attachment, spreading and dendrite outgrowth in melanocytes.
  • Tissue specificity

    Detected in skin keratinocytes and on endothelial cells from skin blood vessels (at protein level). Expressed in fibroblasts, keratinocytes, melanocytes, placenta, testis, ovary, spleen, brain, spinal chord, lung, heart, adrenal gland, lymph nodes, thymus, intestine and kidney.
  • Sequence similarities

    Belongs to the semaphorin family.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 PSI domain.
    Contains 1 Sema domain.
  • Cellular localization

    Cell membrane. Detected in a punctate pattern on the cell membrane of basal and supra-basal skin keratinocytes.
