Potential functions of Protein Domain 2 in a Fusion Protein. This domain usually serves a general function to improve pharmacokinetic and/or pharmacodynamic properties (i.e. Carrier domain). The possible functions may be to (1) increase in vivo stability/plasma half-life, (2) target specific tissues or cells, and/or (3) Facilitate transport or delivery to inaccessible sites.
