Full-length b-nexilin contains an N-terminal F-actin-binding domain (ABD), followed by a spacer, a coiled-coil region, a second ABD, and a long C-terminal tail. In comparison, s-nexilin lacks the N-terminal ABD and has an insertion in the C-terminal tail.

WebA useful model for determining the mechanisms by which actin and actin binding proteins control cellular architecture is the Drosophila melanogaster process of spermatogenesis. … WebCapping protein is involved in actin filament assembly and disassembly. Capping proteins control access to the free barbed ends of actin filaments and is therefore a major factor affecting actin filament elongation. Capping proteins have a high affinity for barbed ends and their micromolar concentration in the cytoplasm ensures that most barbed ...
WebMonomeric G-actin is a 46-kDa globular protein present in all cells, wherein it exists in a dynamic state undergoing polymerization in four stages [140] to form F-actin microfilaments. This, together with the six similar isoforms of G-actin, and a structural model of the F-actin microfilament, are reviewed by Chhabra and dos Remedios [140]. WebActin is a family of globular multi-functional proteins that form microfilaments. An actin protein is the monomeric subunit of two types of filaments in cells: microfilaments, one of …
