Activated factor VIII (FVIIIa) forms a procoagulant complex with factor IXa on negatively charged membranes, including activated platelet surfaces. Membrane attachment involves the FVIII C2 domain; involvement of the adjacent C1 domain has not been established. Binding of recombinant FVIII C1C2 and C2 proteins to platelets was detected by flow cytometry using (1) anti-C2 monoclonal antibody ESH...

MVA-BN-PRO (BN ImmunoTherapeutics) is a candidate immunotherapy product for the treatment of prostate cancer. It encodes 2 tumor-associated antigens, prostate-specific antigen (PSA), and prostatic acid phosphatase (PAP), and is derived from the highly attenuated modified vaccinia Ankara (MVA) virus stock known as MVA-BN. Past work has shown that the immunogenicity of antigens can be improved by...
Extracellular vesicles (EVs) are increasingly being recognized as candidate drug delivery systems due to their ability to functionally transfer biological cargo between cells. However, manipulation of targeting properties of EVs through engineering of the producer cells can be challenging and time-consuming. As a novel approach to confer tumor targeting properties to isolated EVs, we generated ...
Mutations in the cardiac myosin binding protein-C gene (cMyBP-C) are among the most prevalent causes of inherited hypertrophic cardiomyopathy. Although most cMyBP-C mutations cause reading frameshifts that are predicted to encode truncated peptides, it is not known if or how expression of these peptides causes disease. One possibility is that because the N-terminus contains a unique binding sit...
The functional role of the C2 insert of nonmuscle myosin II-C (NM II-C) is poorly understood. Here, we report for the first time that the expression of the C2 insert-containing isoform, NM II-C1C2, is inducible in Neuro-2a cells during differentiation both at mRNA and protein levels. Immunoblot and RT-PCR analysis reveal that expression of NM II-C1C2 peaks between days 3 and 6 of differentiatio...
We have used enzyme kinetics to investigate the molecular mechanism by which the N-terminal domains of human and mouse cardiac MyBP-C (C0C1, C1C2, and C0C2) affect the activation of myosin ATP hydrolysis by F-actin and by native porcine thin filaments. N-Terminal domains of cMyBP-C inhibit the activation of myosin-S1 ATPase by F-actin. However, mouse and human C1C2 and C0C2 produce biphasic act...
The unique myosin binding protein-c "motif" near the N-terminus of myosin binding protein-C (MyBP-C) binds myosin S2. Previous studies demonstrated that recombinant proteins containing the motif and flanking regions (e.g., C1C2) affect thin filament movement in motility assays using heavy meromyosin (S1 plus S2) as the molecular motor. To determine if S2 is required for these effects we investi...
It has been argued that the duration ratio (DR) of two consonants in C1C2 serves as a diagnostic of syllabification: if greater than 1, then C1C2 is a syllable onset; if (approximately) 1, C1C2 is a coda– onset sequence. If valid, this diagnostic would provide a straightforward way of assessing syllabic organization. We examined the validity of the DR using the Wisconsin X-Ray Microbeam corpus,...
