SV40 large T antigen promotes dephosphorylation of p130.

The Journal of biological chemistry - 21 Nov 2003

Lin Jennifer Y, DeCaprio James A

Abstract excerpt

SV40 large T antigen (Ag) binds to all members of the retinoblastoma (RB) tumor suppressor family including pRb, p107, and p130. Although the LXCXE motif of T Ag binds directly to the RB proteins, it is not sufficient to fully inactivate their function. The N-terminal DNA J domain of T Ag cooperates with the LXCXE motif to override RB-mediated repression of E2F-dependent transcription. In addition, T Ag can...
