PTTG2 and cancer: In terms of BP, our analysis revealed significant associations of the PTTG1, PTTG2, and PTTG3P genes with functions such as “cysteine-type endopeptidase inhibitor activity, SH3 domain binding, and endopeptidase inhibitor activity.” These findings suggest potential roles for these genes in the regulation of “proteolytic processes, protein-protein interactions, and cellular signaling pathways” implicated in cancer progression and metastasis.
