Protein Structure

UniProt Annotation

Function

Coreceptor for SEMA3A and SEMA6A. Necessary for signaling by SEMA6A and class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance, invasive growth and cell migration. Class 3 semaphorins bind to a complex composed of a neuropilin and a plexin. The plexin modulates the affinity of the complex for specific semaphorins, and its cytoplasmic domain is required for the activation of down- stream signaling events in the cytoplasm (By similarity). {ECO:0000250}.

Subcellular Localization

Cell membrane {ECO:0000250}; Single-pass type I membrane protein {ECO:0000250}.

Disease Associations

Tissue Specificity

Detected in fetal brain. {ECO:0000269PubMed:8570614}.
