Entrez Gene summary for SEMA7A Gene:

The protein encoded by this gene binds to cell surfaces through a glycosylphosphatidylinositol (GPI) linkage. The

encoded glycoprotein is found on activated lymphocytes and erythrocytes. This protein may be involved in

immunomodulatory and neuronal processes. Defects in this gene can result in loss of bone mineral density (BMD).

Three transcript variants encoding different isoforms have been found for this gene.(provided by RefSeq, Mar

2009)

GeneCards Summary for SEMA7A Gene:

SEMA7A (semaphorin 7A, GPI membrane anchor (John Milton Hagen blood group)) is a protein-coding gene. Diseases associated with SEMA7A include exotropia. GO annotations related to this gene include integrin binding and receptor activity. An important paralog of this gene is SEMA6D.

UniProtKB/Swiss-Prot: SEM7A_HUMAN, O75326

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

Polymorphic Variants from UniProtKB/Swiss-Prot

SEM7A_HUMAN, O75326: Genetic variations in SEMA7A define the John Milton Hagen blood group system (JMH) [MIM:614745].

Three different JMH phenotypes have been identified based on the presence or absence of the high-frequency JMH

antigen: JMH-weak, JMH-negative, and JMH-variant. The JMH-weak and -negative phenotypes can be either acquired or

inherited and are characterized by a reduction or complete loss of JMH expression on red blood cells. Individuals

with the JMH-variant phenotype are usually JMH-positive and have alloantibodies compatible with JMH-negative red

blood cells. The JMH-variant phenotype results from rare SEMA7A missense variants
