Subcellular compartmentalization of adeno-associated virus type 2 assembly.
Using immunofluorescence and in situ hybridization techniques, we studied the intracellular localization of adeno-associated virus type 2 (AAV-2) Rep proteins, VP proteins, and DNA during the course of an AAV-2/adenovirus type 2 coinfection. In an early stage, the Rep proteins showed a punctate distribution pattern over the nuclei of infected cells, reminiscent of replication foci. At this stag...
متن کاملIdentification of a heparin-binding motif on adeno-associated virus type 2 capsids.
Infection of cells with adeno-associated virus (AAV) type 2 (AAV-2) is mediated by binding to heparan sulfate proteoglycan and can be competed by heparin. Mutational analysis of AAV-2 capsid proteins showed that a group of basic amino acids (arginines 484, 487, 585, and 588 and lysine 532) contribute to heparin and HeLa cell binding. These amino acids are positioned in three clusters at the thr...
متن کاملElectron cryo-microscopy and image reconstruction of adeno-associated virus type 2 empty capsids.
Adeno-associated virus type 2 empty capsids are composed of three proteins, VP1, VP2 and VP3, which have relative molecular masses of 87, 72 and 62 kDa, respectively, and differ in their N-terminal amino acid sequences. They have a likely molar ratio of 1:1:8 and occupy symmetrical equivalent positions in an icosahedrally arranged protein shell. We have investigated empty capsids of adeno-assoc...
متن کاملGenetics of adeno-associated virus: isolation and preliminary characterization of adeno-associated virus type 2 mutants.
We constructed insertion and deletion mutants with mutations within the adeno-associated virus (AAV) sequences of the infectious recombinant plasmid pSM620. Studies of these mutants revealed at least three AAV phenotypes. Mutants with mutations between 11 and 42 map units were partially or completely defective for rescue and replication of the AAV sequences from the recombinant plasmids (rep mu...
متن کاملGeneration of Helper Plasmids Encoding Mutant Adeno-associated Virus Type 2 Capsid Proteins with Increased Resistance against Proteasomal Degradation
Objective(s): Adeno-associated virus type 2 (AAV2) vectors are widely used for both experimental and clinical gene therapy. A recent research has shown that the performance of these vectors can be greatly improved by substitution of specific surface-exposed tyrosine residues with phenylalanines. In this study, a fast and simple method is presented to generate AAV2 vector helper plasmids encod...
