Actin-binding membrane proteins are involved in both adhesive interactions and motile processes. We report here the purification and initial characterization of p205, a 205-kD protein from bovine neutrophil plasma membranes that binds to the sides of actin filaments in blot overlays. p205 is a tightly bound peripheral membrane protein that cosediments with endogenous actin in sucrose gradients and immunoprecipitates. Amino acid sequences were obtained from SDS-PAGE-purified p205 and used to generate antipeptide antibodies, immunolocalization data, and cDNA sequence information. The intracellular localization of p205 in MDBK cells is a function of cell density and adherence state. In subconfluent cells, p205 …

Cell-substrate contacts, called focal adhesions (FAs), are dynamic in rapidly moving cells. We show that supervillin (SV)--a peripheral membrane protein that binds myosin II and F-actin in such cells--negatively regulates stress fibers, FAs, and cell-substrate adhesion. The major FA regulatory sequence within SV (SV342-571) binds to the LIM domains of two proteins in the zyxin family, thyroid receptor-interacting protein 6 (TRIP6) and lipoma-preferred partner (LPP), but not to zyxin itself. SV and TRIP6 colocalize within large FAs, where TRIP6 may help recruit SV. RNAi-mediated decreases in either protein increase cell adhesion to fibronectin. TRIP6 partially rescues SV effects on stress …

Detergent-resistant membranes contain signaling and integral membrane proteins that organize cholesterol-rich domains called lipid rafts. A subset of these detergent-resistant membranes (DRM-H) exhibits a higher buoyant density ( approximately 1.16 g/ml) because of association with membrane skeleton proteins, including actin, myosin II, myosin 1G, fodrin, and an actin- and membrane-binding protein called supervillin (Nebl, T., Pestonjamasp, K. N., Leszyk, J. D., Crowley, J. L., Oh, S. W., and Luna, E. J. (2002) J. Biol. Chem. 277, 43399-43409). To characterize interactions among DRM-H cytoskeletal proteins, we investigated the binding partners of the novel supervillin N terminus, specifically amino acids 1-830. We …

A growing number of actin-associated membrane proteins have been implicated in motile processes, adhesive interactions, and signal transduction to the cell nucleus. We report here that supervillin, an F-actin binding protein originally isolated from bovine neutrophil plasma membranes, contains functional nuclear targeting signals and localizes at or near vinculin-containing focal adhesion plaques in COS7-2 and CV1 cells. Overexpression of full-length supervillin in these cells disrupts the integrity of focal adhesion plaques and results in increased levels of F-actin and vinculin. Localization studies of chimeric proteins containing supervillin sequences fused with the enhanced green fluorescent protein indicate that: (1) the amino …
Detection Of Coxiella Burnetii In Cattle By Pcr, Şükrü Kirkan, Osman Kaya, Serten Tekbiyik, Uğur Parin
Detection Of Coxiella Burnetii In Cattle By Pcr, Şükrü Kirkan, Osman Kaya, Serten Tekbiyik, Uğur Parin
Turkish Journal of Veterinary & Animal Sciences
This study is aimed to detect Coxiella burnetii in cattle by Polymerase Chain Reaction (PCR). A total of 138 cattle blood samples were collected from 8 farms and then examined in laboratory conditions. The examination of Coxiella burnetii was carried out by PCR with specific primers. In this study, a total of 6 (4.3%) cattle serum samples were found PCR positive for Coxiella burnetii. This result proves that cattle are an important reservoir of Coxiella burnetii infection.
Clinical And Haematological Findings In Bovine Immunodeficiency Virus (Biv) Infected Cattle, Zeki̇ Yilmaz, Kadi̇r Yeşi̇lbağ
Clinical And Haematological Findings In Bovine Immunodeficiency Virus (Biv) Infected Cattle, Zeki̇ Yilmaz, Kadi̇r Yeşi̇lbağ
Turkish Journal of Veterinary & Animal Sciences
The clinical and haematological findings in dairy cattle with naturally infected bovine immunodeficiency virus (BIV) infection were evaluated. Thirty-seven (12.3%) out of 300 cattle that had previously been found positive for BIV infection were monitored. Thirty-seven BIV-free cattle selected from BIV-positive herds were used as a control group. Routine clinical and haematological parameters were recorded 6 times, at 1-month intervals. Mastitis (n = 18), metritis (n = 9), respiratory system diseases (n = 8), retained placenta (n = 7), and regional lymphadenopathy (n = 7) were predominantly diagnosed during the monitoring period in BIV-infected cattle, and mastitis (n = 1) …
Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin
Production Losses Due To Endemic Foot-And-Mouth Disease In Cattle In Turkey, Berri̇n Şentürk, Cengi̇z Yalçin
Turkish Journal of Veterinary & Animal Sciences
This research paper is aimed at estimating foot-and-mouth disease (FMD)-induced production losses in individual dairy and fattening cattle in Turkey. The data used were obtained from a Delphi Expert Opinion Survey. The weighted average FMD-induced financial losses for all breeds were estimated to be $294/head for a milking cow, $152/head for a dairy heifer and $197/head for beef cattle. However, the amount of financial loss varied across different breeds, ages, and sexes. The study findings suggest that culling Holstein breed cows, beef cattle, and Holstein and cross breed female calves, as soon as they have an FMD infection, would be …
