Protein

Semaphorin-7A

Gene

Sema7a

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.3 Publications

Disruption phenotypei

No visible phenotype. Mice display normal levels of lymphocytes in spleen, and normal activation of T-cells by antigenic stimuli. In contrast, production of proinflammatory cytokines by macrophages is much reduced. The effect on contact hypersensitivity and experimental autoimmune encephalomyelitis is controversial. Reduced size of the lateral olfactory tract.3 Publications

Caution

The exact role in regulating T-cell function is under debate. According to (PubMed:16713976), SEMA7A-deficient mice are highly susceptible to contact hypersensitivity and experimental autoimmune encephalomyelitis. According to (PubMed:17377534) mice do not develop contact hypersensitivity, and are highly resistant to experimental autoimmune encephalomyelitis.2 Publications
