In order to determine a cellular localization of protein kinase StkP we prepared its epitope-labelled form expressed in S. pneumoniae. The full-length form of StkP was detected with monoclonal antibody in the membrane fraction. In vitro autophosphorylation assays confirmed this finding and phosphorylated product of corresponding mass was detected in the membranes. These results clearly showed that StkP is a membrane-associated protein.

Byla určena buněčná lokalizace proteinkinasy StkP pomocí integrace do genomu S. pneumoniae jejího genu označeného epitopem. Nativní forma StkP byla detekována monoklonální protilátkou v membránové frakci. Tento výsledek byl ověřen in vitro autofosforylací a fosforylovaný produkt odpovídající velikosti byl detekován v membránách.
