Fig. 1 kcng4b-C1 and kcng4b-C2 mutations differently affect Kcng4b’s C-terminal. A - kcng4b nucleotide sequence is in black, stop-codons are in red, gRNAs' PAM-sequences are in blue, and deleted nucleotides are in orange. The Kcng4b amino-acid sequence is in green, the modified one in lilac. B - mutation kcng4b-C1 caused Kcng4b C-terminal truncation. C - mutation kcng4b-C2 caused an extension of Kcng4b polypeptide and formation of an additional C-terminal TM domain (S7, underlined). T1 and CTA – N- and C-terminal cytoplasmic domains, S1–S7 – TM domains. IN, OUT – intracellular and extracellular space.
