Cordon-Bleu: A New Taste in Actin Nucleation
Polymerization of actin filaments powers many dynamic cellular events and is directed by a small group of actin nucleators. In this issue, Ahuja et al. (2007) identify and characterize a new actin nucleator called cordon-bleu (Cobl) that may drive morphogenesis of the central nervous system during development.
متن کامل16-P014 Cordon-bleu is a developmentally regulated, novel actin nucleator that plays a role in epithelial ciliogenesis
genes that control motor neuron induction, subtype identity, and target specificity. Mice were mutagenized with ENU and outcrossed to an HB9-GFP transgenic reporter line that expresses GFP in spinal motor neurons and their axons. Litters were analyzed by fluorescence microscopy for recessive mutations that affect motor neuron induction and motor axon projection pattern. We have screened 137 F1 ...
متن کاملCordon-Bleu Is an Actin Nucleation Factor and Controls Neuronal Morphology
Despite the wealth of different actin structures formed, only two actin nucleation factors are well established in vertebrates: the Arp2/3 complex and formins. Here, we describe a further nucleator, cordon-bleu (Cobl). Cobl is a brain-enriched protein using three Wiskott-Aldrich syndrome protein homology 2 (WH2) domains for actin binding. Cobl promotes nonbundled, unbranched filaments. Filament...
متن کاملCordon-Bleu uses WH2 domains as multifunctional dynamizers of actin filament assembly.
Cordon-Bleu is, like Spire, a member of the growing family of WH2 repeat proteins, which emerge as versatile regulators of actin dynamics. They are expressed in morphogenetic and patterning processes and nucleate actin assembly in vitro. Here, we show that Cordon-Bleu works as a dynamizer of actin assembly by combining many properties of profilin with weak filament nucleating and powerful filam...
متن کاملThe master cell cycle regulator APC-Cdc20 regulates ciliary length and disassembly of the primary cilium
The primary cilium has an important role in signaling; defects in structure are associated with a variety of human diseases. Much of the most basic biology of this organelle is poorly understood, even basic mechanisms, such as control of growth and resorption. We show that the activity of the anaphase-promoting complex (APC), an E3 that regulates the onset of anaphase, destabilizes axonemal mic...
