Recombinant Simian Immunodeficiency Virus VPX Protein (1-112 aa), His-SUMO-tagged

• Cat.No.: VPX-882S
• Product Overview: Recombinant Simian Immunodeficiency Virus (isolate K78) (SIV-mac) VPX Protein (1-112 aa) is produced by E. coli expression system. This protein is fused with a 6xHis-SUMO tag at the N-terminal. Protein Description: Full Length.

Specification

• Species: Simian Immunodeficiency Virus
• Source: E.coli
• Tag: His&SUMO
• Protein Length: 1-112 aa
• Description: Plays a role in nuclear translocation of the viral pre-integration complex (PIC), thus is required for the virus to infect non-dividing cells. Targets specific host proteins for degradation by the 26S proteasome. Acts by associating with the cellular CUL4A-DDB1 E3 ligase complex through direct interaction with host VPRPB/DCAF-1. This change in the E3 ligase substrate specificity results in the degradation of host SAMHD1. In turn, SAMHD1 depletion allows viral replication in host myeloid cells by preventing SAMHD1-mediated hydrolysis of intracellular dNTPs necessary for reverse transcription.
