Based on the provided abstracts, there is insufficient information to provide a comprehensive gene function summary for EMB (embigin). The abstracts primarily discuss EMB as an abbreviation for endomyocardial biopsy rather than the embigin gene 123. However, limited functional evidence is available: EMB appears to play a role in enteric nervous system (ENS) development by regulating proliferation and migration of enteric neural crest cells through PI3K-AKT signaling pathway activation 4. Mechanistically, EMB recruits the phosphatase complex PP2A to the cellular membrane, reducing cytoplasmic dephosphorylation activity and promoting PI3K pathway activation 4. In disease contexts, EMB variants may contribute to Hirschsprung's disease pathology 4, and a common variant (rs3933097) in the 3'-UTR shows association with schizophrenia risk 5. Additionally, EMB is highly expressed in glioblastoma multiforme and associated with poor prognosis, potentially driving tumor progression through epithelial-mesenchymal transition and metabolic reprogramming 6. The available evidence is limited and primarily focused on specific disease contexts rather than comprehensive gene function.
