Specificity
In biosgnalling, all information transfer
need to be very precisely and correctly targeted to cells
where the specificity comes
from
1.ligand-receptor protein structure
complementarity
1.1 involve weak noncovalent
forces
2.Receptors are expressed in
certain types of cell
3.Some
down-stream mechanisms to be regulated only exist in certain types of
cell
