Expression Patterns of The Transcript and The Protein Subtypes of PKM. a That there are 14 different subtype sequences in the PKM gene transcript, and there are some differences between them, among which the PKM1 (No. 3 and No. 5) and PKM2 (No. 2) subtypes are more compared, b the coding sequence NO. 12 expresses PKM1 and the coding sequence expresses NO. 13 PKM2. There are only 23 amino acid residues between the two protein sequences. And there are few studies on other PKM protein subtypes, and the functions are not sure yet
