More Details: Ethanol-soluble proteins, including prolamins, are one of the most important seed proteins in rice (Oryza sativa L.). However, little is known about the proteomic profile of ethanol-soluble protein fraction extracted from rice grain. In this work, the differential profile of ethanol-soluble proteins extracted by 2-chloroethanol and ethanol has been documented. Proteome analysis utilizing LC-MS/MS identified a total of 64 unique proteins in the 2-chloroethanol extract of rice seeds. The majority of these proteins had low molecular weight ranging from 10 to 25 kD and isoelectric point (pI) in mid-acidic (pH 5–pH 7) and mid-basic (pH 7–pH 9) ranges. Database searches combined with transmembrane domain (TMD) analysis revealed that >70% of identified proteins were hydrophobic, i.e., had at least one TMD. Gene ontology classification and enrichment analysis showed that the identified proteins were involved in13 types of biological processes, 5 types of cell components, and 17 types of molecular functions. These results were significant based on the hyper p-value of
