Negative control image : IHC image of Semaphorin 7a staining in a section of human normal frozen liver* performed on a Leica Biosystems BOND® RX instrument using the standard protocol. The section was fixed in 10% paraformaldehyde (10 min) prior to staining. The section was incubated with ab225602, 1ugml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody. *Tissue obtained from the Human Research Tissue Bank, supported by the NIHR Cambridge Biomedical Research Centre For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Supplementary information

Semaphorin 7a also known as SEMA7A or CD108 is a glycoprotein that has a molecular mass of approximately 80 kDa. This target plays a role in axonal guidance and immune response regulation. It is a member of the semaphorin family which generally acts as signaling molecules. Semaphorin 7a is expressed in various tissues including the immune system nervous system and some epithelial cells. Its expression is especially significant in T-cells and is involved in modulating cell adhesion and migration.
Biological function summary

Semaphorin 7a is implicated in diverse processes such as immune system modulation and nervous system development. It functions as part of a complex involving integrins which mediate cell-to-cell communication and interaction with the extracellular matrix. This protein can bridge the immune and neural signaling pathways indicating its multifunctional nature within organisms. Its interaction with β1 integrins enhances T-cell activation and cytokine production which is important for immune response.

Pathways

Semaphorin 7a integrates into the MAPK and PI3K signaling pathways. These pathways are essential for cell survival migration and apoptosis. In the MAPK pathway Semaphorin 7a impacts downstream signaling through its interaction with ERK proteins. Its role in the PI3K pathway connects it to AKT proteins influencing cell growth and metabolic processes. These connections show its versatility and critical role in signal transduction linked to cellular behaviors.

Semaphorin 7a has been associated with multiple sclerosis and melanoma. In multiple sclerosis altered expression of this protein can affect immune response and neural repair processes. Its connection to melanoma is linked with its role in regulating cell motility and adhesion impacting cancer progression and metastasis. Semaphorin 7a's interactions with proteins like Melanocortin 1 Receptor (MC1R) in melanoma provide insights into therapeutic targets for disease interventions.
