Pokeweed antiviral protein II (PAP-II) is a naturally occurring protein isolated from early summer leaves of the pokeweed plant (Phytolacca americana). PAP-II belongs to a family of ribosome-inactivating proteins which catalytically deadenylate ribos

Pokeweed antiviral protein (PAP) is a naturally occurring broad-spectrum antiviral agent with potent anti-human immunodeficiency virus (HIV)-1 activity by an as yet undeciphered molecular mechanism. In the present study, we sought to determine if PAP

The investigational biotherapeutic agent, B43(anti-CD19)-pokeweed antiviral protein (PAP) immunotoxin, has shown substantial anti-leukemic activity in SCID mouse models of human B-lineage leukemia and lymphoma. In this report, we describe the results

Standard immunotoxin production procedures using whole IgG as the MoAb moiety yield a heterogeneous mixture of 180 kDa, 210 kDa, and 240 kDa immunotoxin species with 1 to 1, 1 to 2, and 1 to 3 MoAb to toxin ratios. This heterogeneity makes it impossi

Pokeweed antiviral protein (PAP) and other ribosome-inactivating proteins (RIPs) had previously been thought to be incapable of attacking conspecific ribosomes, thus having no effect on endogenous processes. This assertion conflicts with a model for

We have successfully constructed highly potent and selective anti-CD19 PAP immunotoxins using each of the three crosslinking agents, SPDP, LC-SPDP, or SMPT, to generate an intermolecular bridge between the B43 MoAb and PAP toxin moieties. These immun

Infection of HeLa cells with poliovirus results in cell permeabilization to pokeweed antiviral protein. Cell permeabilization was dependent on the integrity of virus capsid proteins and directly proportional to the multiplicity of infection. This stu

The pokeweed antiviral protein (PAP), isolated from the leaves of Phytolacca americana, is one of a family of plant and bacterial ribosome-inhibiting proteins (RIPs) which act as specific N-glycosidases on rRNA. Here we report the three-dimensional s

Pokeweed antiviral protein (PAP) is a ribosome-inactivating protein (RIP) that inactivates ribosomes by the removal of a single adenine from ribosomal RNA. The studies summarized in our review concern the nature and application of this novel therapeu

We describe a standardized method for the preparation and purification of a potent immunotoxin against B-lineage leukemia/lymphoma cells, constructed with the ribosome inhibitory single chain plant toxin pokeweed antiviral protein (PAP) and a murine
