[HTML][HTML] Prothymosin α interacts with the CREB‐binding protein and potentiates transcription

Z Karetsou, A Kretsovali, C Murphy, O Tsolas… - EMBO …, 2002 - embopress.org
Prothymosin α (ProTα) is a histone H1‐binding protein localized in sites of active
transcription in the nucleus. We report here that ProTα physically interacts with the CREB‐binding …

Prothymosin α modulates the interaction of histone H1 with chromatin

Z Karetsou, R Sandaltzopoulos… - Nucleic acids …, 1998 - academic.oup.com
Prothymosin α (ProTα) is an abundant acidic nuclear protein that may be involved in cell
proliferation. In our search for its cellular partners, we have recently found that ProTα binds to …

[HTML][HTML] Prothymosin α associates with the oncoprotein SET and is involved in chromatin decondensation

Z Karetsou, G Martic, S Tavoulari, S Christoforidis… - FEBS letters, 2004 - Elsevier
… Furthermore, direct binding of SET with CBP has been detected (Karetsou et al., unpublished
data). On the basis of these findings, we suspected that CBP might exist in the ProTα/SET …

Identification of distinct SET/TAF-Iβ domains required for core histone binding and quantitative characterisation of the interaction

Z Karetsou, A Emmanouilidou, I Sanidas, S Liokatis… - BMC biochemistry, 2009 - Springer
