脱氧胞苷脱氨酶蛋白抗体产品介绍 

Function : DNA deaminase (cytidine deaminase) which acts as an inhibitor of retrovirus replication and retrotransposon mobility via deaminase-dependent and -independent mechanisms. Exhibits potent antiviral activity against vif-deficient HIV-1. After the penetration of retroviral nucleocapsids into target cells of infection and the initiation of reverse transcription, it can induce the conversion of cytosine to uracil in the minus-sense single-strand viral DNA, leading to G-to-A hypermutations in the subsequent plus-strand viral DNA. The resultant detrimental levels of mutations in the proviral genome, along with a deamination-independent mechanism that works prior to the proviral integration, together exert efficient antiretroviral effects in infected target cells. Selectively targets single-stranded DNA and does not deaminate double-stranded DNA or single-or double-stranded RNA. Exhibits antiviral activity also against simian immunodeficiency viruses (SIVs), hepatitis B virus (HBV), equine infectious anemia virus (EIAV), xenotropic MuLV-related virus (XMRV) and simian foamy virus (SFV). May inhibit the mobility of LTR and non-LTR retrotransposons.

Subunit : Homodimer. Homooligomer. Can bind RNA to form ribonucleoprotein complexes of high-molecular-mass (HMM) or low-molecular-mass (LMM). HMM is inactive and heterogeneous in protein composition because of binding nonselectively to cellular RNAs, which in turn are associated with variety of cellular proteins. The LMM form which is enzymatically active has few or no RNAs associated. Its ability to form homooligomer is distinct from its ability to assemble into HMM. Interacts with APOBEC3B, APOBEC3F, MOV10, EIF2C2/AGO2, EIF4E, EIF4ENIF1, DCP2 and DDX6 in an RNA-dependent manner. Interacts with EIF2C1/AGO1, EIF2C3/AGO3 and PKA/PRKACA. Interacts with HIV-1 VIF and reverse transcriptase/ribonuclease H. Interacts with hepatitis B virus capsid protein.

Subcellular Location : Cytoplasm. Nucleus. Cytoplasm, P-body. Note=Mainly cytoplasmic. Small amount are found in the nucleus. During HIV-1 infection, virion-encapsidated in absence of HIV-1 VIF.

Tissue Specificity : Expressed in spleen, testes, ovary and peripheral blood leukocytes and CD4+ lymphocytes. Also expressed in non-permissive peripheral blood mononuclear cells, and several tumor cell lines; no expression detected in permissive lymphoid and non-lymphoid cell lines. Exists only in the LMM form in peripheral blood-derived resting CD4 T-cells and monocytes, both of which are refractory to HIV-1 infection. LMM is converted to a HMM complex when resting CD4 T cells are activated or when monocytes are induced to differentiate into macrophages. This change correlates with increased susceptibility of these cells to HIV-1 infection.

Post-translational modifications : Ubiquitinated in the presence of HIV-1 VIF. Association with VIF targets the protein for proteolysis by the ubiquitin-dependent proteasome pathway.

Phosphorylation at Thr-32 reduces its binding to HIV-1 VIF and subsequent ubiquitination and degradation thus promoting its antiviral activity.

Similarity : Belongs to the cytidine and deoxycytidylate deaminase family.

Contains 2 CMP/dCMP deaminase zinc-binding domains.
