FBXW7-AS1 and cancer: Altogether, in the context of an error prone site at codon#14, multiple protein assays independently and collectively demonstrate the existence of the DEspR protein, and analyses that show DEspR protein properties (protein–protein interactions, glycosylation, internalization) and functional roles in multiple cancer tissue type CSCs, collectively certify the DEspR protein based on multiple UNIPROT criteria and demonstrate that the human DEspR gene is not a pseudogene.
