27. PTMA associates with SET and is involved in chromatin decondensation. PMID: 15556635
28. Prothymosin alpha functions as intranuclear dissociator of the Nrf2-Keap1 complex. PMID: 15657435
29. PTMA expression is intimately involved in the differentiation and progression of human prostate cancers, and could be a target for therapy and diagnostic purposes. PMID: 16353248
30. Antiapoptotic response of cells requires expression of both p8 and ProTalpha. PMID: 16478804
31. the anti-apoptotic effect previously attributed separately to p8 and prothymosin alpha is in fact borne by the p8/ProTalpha complex, the two proteins being individually inactive PMID: 16628001
