Ponticulin plays a role in the positional stabilization of pseudopods (1995)
Shutt, D. C., Wessels, D., Wagenknecht, K., Chandrasekhar, A., Hitt, Anne L., Luna, Elizabeth J., ...
Ponticulin is a 17-kD glycoprotein that represents a major high affinity link between the plasma membrane and the cortical actin network of Dictyostelium. To assess the role of ponticulin in...
Ponticulin is an atypical membrane protein (1994)
Hitt, Anne L., Lu, Tze Hong, Luna, Elizabeth J.
We have cloned and sequenced ponticulin, a 17,000-dalton integral membrane glycoprotein that binds F-actin and nucleates actin assembly. A single copy gene encodes a developmentally regulated message...
Hitt, Anne L., Hartwig, J. H., Luna, Elizabeth J.
Interactions between the plasma membrane and underlying actin-based cortex have been implicated in membrane organization and stability, the control of cell shape, and various motile processes. To...
Cytoskeleton--plasma membrane interactions (1992)
Luna, Elizabeth J., Hitt, Anne L.
Proteins at the boundary between the cytoskeleton and the plasma membrane control cell shape, delimit specialized membrane domains, and stabilize attachments to other cells and to the substrate....
Direct binding of F-actin to ponticulin, an integral plasma membrane glycoprotein (1991)
Chia, C. P., Hitt, Anne L., Luna, Elizabeth J.
We have developed an 125I-labeled F-actin blot overlay assay for the identification of F-actin-binding proteins after transfer to nitrocellulose from SDS-polyacrylamide gels. Two major...
