Connexin31(Cx31) is a member of the Connexin family. Currently,
little is known about the function and regulation mode of Cx31. In this study, the
phosphorylation sites of Cx31 in mice were determined by immunoprecipitation,
sds-page separation, protein strip recovery, protein block enzymolysis,
phenylisothiocyanate modification, psd-maldi-tof mass spectrometry, and data
analysis.
