Putative gene

It refers to a nucleotide sequence believed to be a gene because of its open reading frame although its function and the protein it codes for has not been (fully) identified [1]. For example, putative gene 57 is the (temporary) name suggested for the gene coding for a protein produced by Bacteriophage SP01 that infects the bacterium Bacillus subtilis [2]. Another example: PTEN, a putative protein tyrosine phosphatase gene mutated in some cancers [3].
