Tks5-dependent formation of circumferential podosomes/invadopodia mediates cell–cell fusion
Osteoclasts fuse to form multinucleated cells during osteoclastogenesis. This process is mediated by dynamic rearrangement of the plasma membrane and cytoskeleton, and it requires numerous factors, many of which have been identified. The underlying mechanism remains obscure, however. In this paper, we show that Tks5, a master regulator of invadopodia in cancer cells, is crucial for osteoclast f...
متن کاملThe SRC substrate Tks5, podosomes (invadopodia), and cancer cell invasion.
Some years ago, we employed a screen of phage cDNA expression libraries to identify novel substrates of the protein tyrosine kinase Src. One of these, Tks5 (previously known as Fish), is a large scaffolding protein with an amino-terminal PX domain and five SH3 domains. In normal fibroblasts, Tks5 is cytoplasmic, but the protein is found in podosomes when the cells are transformed with Src. Usin...
متن کاملDystroglycan, Tks5 and Src Mediated Assembly of Podosomes in Myoblasts
BACKGROUND Dystroglycan is a ubiquitously expressed cell adhesion receptor best understood in its role as part of the dystrophin glycoprotein complex of mature skeletal muscle. Less is known of the role of dystroglycan in more fundamental aspects of cell adhesion in other cell types, nor of its role in myoblast cell adhesion. PRINCIPAL FINDINGS We have examined the role of dystroglycan in the...
متن کاملPossible role of IRTKS in Tks5-driven osteoclast fusion
Podosomes and invadopodia seen in osteoclasts and cancer cells, respectively, are actin-rich membrane protrusions. We recently demonstrated that an adaptor protein, Tks5, which is an established regulator of invadopodia in cancer cells, drives osteoclast-osteoclast fusion as well as osteoclast-cancer cell fusion by generating circumferential podosomes/invadopodia. This finding revealed an unexp...
