Demonstrating both the TM4 (panel A) and Cx43CT (panel B) domains from the TM4-Cx43CT polypeptide are in a properly folded conformation. (A) The control 15N-HSQC, TM4-Cx43CT alone (black), has been overlapped with a spectrum obtained when the TM4-Cx43CT and c-Src SH3 domain were present at a 1:3 molar ratio (red). (B) Circular dichroism spectra of the TM4-Cx43CT and a soluble version of the Cx43CT without the TM4 domain. The spectra are represented as mean residue ellipticity. The TM4-Cx43CT and the soluble Cx43CT are labeled in the panel.
