PubMed Abstract:
Phosphatidylethanolamine-binding protein (PEBP) is a basic protein found in numerous tissues from a wide range of species. The screening of gene and protein data banks defines a family of PEBP-related proteins that are present in a variety of organisms, including Drosophila and inferior eukaryotes. PEBP binds to phosphatidylethanolamine and nucleotides in vitro, but its biological function in vivo is not yet known. The expression of PEBP and related proteins seems to be correlated with development and cell morphogenesis, however. To obtain new insights into the PEBP family and its potential functions, we initiated a crystallographic study of bovine brain PEPB.
