phosphatidylethanolamine binding protein
Summary: A ubiquitously found basic protein that binds to phosphatidylethanolamine and NUCLEOTIDES. It is an endogenous inhibitor of RAF KINASES and may play a role in regulating SIGNAL TRANSDUCTION. Phosphatidylethanolamine-binding protein is the precursor of hippocampal cholinergic neurostimulating peptide, which is cleaved from the N-terminal region of the protein.
