NCBI Protein Information
VIRE2-interacting protein 1
NCBI Summary
Encodes a VirE2-interacting protein. VIP1 mediates nuclear translocation of VirE2 via its amino half, and interacts with histone H2A via it carboxyl half. Involved in osmosensory response.

UniProt Comments
Transcription activator that binds specifically to the VIP1 response elements (VREs) DNA sequence 5'-ACNGCT-3' found in some stress genes (e.g. TRX8 and MYB44), when phosphorylated/activated by MPK3. Required for Agrobacterium VirE2 nuclear import and tumorigenicity. Promotes transient expression of T-DNA in early stages by interacting with VirE2 in complex with the T-DNA and facilitating its translocation to the nucleus, and mediates stable genetic transformation by Agrobacterium by binding H2A histone. Prevents cell differentiation and shoot formation. Limits sulfate utilization efficiency (SUE) and sulfate uptake, especially in low-sulfur conditions.
