ABSTRACT
Objective To identify novel proteins of human adipocytes by proteomic study,and analyze their strueture and function.Methods The expressed proteins of human adipocytes were identified by 2-D electrophoresis and mass spectrometry,and the structure and function of the novel proteins were predicated via bioinforrnatics.Results My027 is a novel protein of human adipocytes identified by 2-D electrophoresis and mass spectrometry.This protein was confirmed by RT-PCR,sequencing,and prokaryotic expression.My027 protein is located in the cytoplasm and has highly conserved structure,indicating that it is an important functional protein. This protein is highly homologous to glyoxalase superfamily with a whole domain of glyoxalase.It shares 96.7% homologous to glycoxalase between 141-253 amino acids and 95.7% homologous to glycoxalaseⅠbetween 144-244 amino acids.Conclusion The results show that protein My027 appears to have the same function as glyoxalaseⅠ.
