Structural analysis of the KIS-deletion protein KChIP4a(Δ1–42). A, ¹H-¹⁵N TROSY spectrum of the Ca²⁺ and Mg²⁺-loaded KChIP4a(Δ1–42) as in Fig. 1A. The cross peak at 8.64/121.45 ppm marked with an asterisk corresponds to Val¹³⁶. B, sequence, secondary structure, and schematic representation of NMR data of KChIP4a(Δ1–42) as in Fig. 2A.
