SEMA3E
Overview
SEMA3E (semaphorin 3E) encodes a secreted class-3 semaphorin involved in axon guidance, acting through plexin receptors. In pancreatic ductal adenocarcinoma, SEMA3E is co-amplified with SEMA3A, suggesting coordinate dysregulation of semaphorin signaling contributes to PDAC pathogenesis.
