Key result
Chemically synthesized KChIP2d is primarily alpha-helical, becomes more structured upon binding calcium, and exists in a monomer-dimer equilibrium in solution.
Population

Offers no immediate clinical guidance on ion channel function; extends structural data on KChIP2d and leaves open its cardiac relevance.
The successful chemical synthesis and biophysical characterization of KChIP2d provides a foundation for probing its mechanism in regulating cardiac transient outward potassium currents.
Rajagopal et al. (2007) studied this question. Chemical synthesis of KChIP2d was evaluated on Biophysical characterization (structure, calcium binding, monomer-dimer equilibrium). Chemically synthesized KChIP2d is primarily alpha-helical, becomes more structured upon binding calcium, and exists in a monomer-dimer equilibrium in solution.
