Required for uptake of DNA by competent cells. Localizes mostly to the cell poles during the development of competence, this depends on comK. During competence a number of proteins (at least CoiA, ComFA, ComGA, DprA, RecA and SsbB) are thought to colocalize at the cell pole, when comFA is disrupted ComGA no longer accumulates (PubMed:16009133). Colocalizes with CoiA and DprA (PubMed:17630974). During development of competence ComGA and SsbB colocalize in discrete foci which accumulate at the cell poles and then delocalize without the overall levels of proteins decreasing, these processes are coincident with the timing of transformability and the site of DNA uptake (PubMed:16009133). Expressed in cells competent for DNA transformation; that is 5-15% of the population (PubMed:11918817, PubMed:16009133, PubMed:17630974). Expression activated by ComK (PubMed:11918817, PubMed:11948146). Transformation deficient (PubMed:16009133). Belongs to the GSP E family.
