Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg\/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃\/-80℃. Our default final concentration of glycerol is 50%.

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 (By similarity).\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: \"Identification of the nuclear localization signal of human immunodeficiency virus type 2 Vpx.\"Belshan M., Ratner L.Virology 311: 7-15(2003)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFunction\u003c\/b\u003e: Plays a role in nuclear translocation of the viral pre-integration complex (PIC), thus is required for the virus to infect non-dividing cells.
