The CDS of the shortest isoform of human gene 'A' is cloned into a 3.3 kb vector under a CMV promoter at the BamHI and Xhol sites (pCMV-A vector).
From the agarose gel and SDS-PAGE images shown above, which one of the following is most likely true for protein A in HeLa cells:
1
Protein A forms homo-multimers.
2
Protein A is degraded by the lysosome.
3
Protein A is polyubiquitinated.
4
Protein A localizes to autophagosomes.
