Subunit structurei
Interacts with host UBE2I; this interaction interferes with polySUMOylation.
Interacts with host RB1; this interaction induces the aberrant dissociation of RB1-E2F1 complex thereby disrupting the activity of RB1 and activating E2F1-regulated genes.
Interacts with host ATF7; the interaction enhances ATF7-mediated viral transactivation activity which requires the zinc binding domains of both proteins (PubMed:8417352). Isoform early E1A 32 kDa protein and isoform early E1A 26 kDa protein interact (via N-terminus) with CUL1 and E3 ubiquitin ligase RBX1; these interactions inhibit RBX1-CUL1-dependent elongation reaction of ubiquitin chains and attenuate ubiquitination of SCF(FBXW7) target proteins.
Interacts (via PXLXP motif) with host ZMYND11/BS69 (via MYND-type zinc finger); this interaction inhibits E1A mediated transactivation.
Interacts with host EP300; this interaction stimulates the acetylation of RB1 by recruiting EP300 and RB1 into a multimeric-protein complex.
Interacts with host CTBP1 and CTBP2; this interaction seems to potentiate viral replication.
Interacts with host DCAF7.
Interacts with host DYRK1A.
Interacts with host KPNA4; this interaction allows E1A import into the host nucleus.
Interacts with host EP400; this interaction stabilizes MYC.
Interacts (via LXCXE motif) with host TMEM173/STING; this interaction impairs the ability of TMEM173/STING to sense cytosolic DNA and promote the production of type I interferon (IFN-alpha and IFN-beta) (By similarity).
Interacts (via C-terminus) with host ZBED1/hDREF (via C-terminus); the interaction is direct (By similarity).
