TABLE 2.
Summary of the observed levels of the three known Dictyostelium secreted group size-regulatory proteins in CM
| Protein | Level in the indicated cell typea
|
||||
|---|---|---|---|---|---|
| smlA− | WT | countin− | cf45-1− | cf50− | |
| CF50 | ++ | + | +++ | +++ | − |
| CF45-1 | ++ | + | +++ | − | +++ |
| Countin | +++ | + | − | Variable | Variable |
a
−, none observed; +, level seen in CM from wild type (WT) cells; ++, higher level than that seen with WT cells; +++, considerably higher level than that seen with WT cells. Variable indicates that for unknown reasons, cultures can have low levels along with degradation products, levels comparable to those seen in CM from WT cells, or even higher levels than those in CM from WT cells. Results are as indicated by Western blotting.
