Netrin-1 Peptide Is a Chemorepellent in Tetrahymena thermophila
A comparison of polycationic peptides and proteins which are chemorepellents in Tetrahymena. Calcium is required for avoidance of all of the compounds listed except for netrin-1 peptide, suggesting a unique signaling mechanism for this peptide. Netrin-1 peptide also has one of the lowest EC100 values of the polycationic compounds studied to date, suggesting a high affinity for its putative receptor.
Charge at pH 7.0
Calcium required for avoidance?
