  • 產(chǎn)品描述：

    The first step of making this recombinant Human SEMA7A?protein is synthesizing the SEMA7A?gene, the synthesized gene is then cloned into an expression vector which is a cDNA plasmid that includes a promoter sequence and an antibiotic-resistant gene. It also has N-terminal 6xHis tag?encoding a fusion tag for downstream protein purification or identification. The antibiotic-resistant gene enables the selection of cells carrying the plasmid in antibiotic-based media and then transfects cells with a DNA vector that contains the template and then culturing the cells so that they transcribe and translate the desired protein. The recombinant SEMA7A protein is purified by ion-exchange chromatography or affinity purification. And the purity is 90%+ by SDS-PAGE.

    SEMA7A plays a role in both innate and adaptive immune systems. It is a strong stimulator of monocytes in innate immunity, inducing the generation of pro-inflammatory cytokines. While SEMA7A works as a regulator of the T-cell immune response in adaptive immunity due to its effects on T-cell proliferation. SEMA7A can regulate T cell responses via the α1β1 integrin receptor. SEMA7A is a glycosylphosphatidylinositol (GPI)-anchored membrane protein with chemoattractant and chemorepulsive attributes. In addition to its role in guiding axon pathfinding during neuronal development, SEMA7A has diverse functions in morphogenesis and immune cell control.

  • 功能：
    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.
