Last, SLC6A20 was found to interactwith an ACE2 homologue protein TMEM27, and TMEM27 was upregulatedin different cancer types along with its being positively correlatedpredominantly with ACE2 and TMPRSS2, which are known SARS-CoV-2-associatedproteins. This evidence concerns the gene TMPRSS2 and cancer.
