Dynein proteins that lack stalk domains
WebMar 30, 2024 · Cytoplasmic dynein-2 (hereafter referred to as dynein-2) is an ATP-dependent motor protein that steps along microtubules to transport cargoes within cilia and flagella ().It is related to cytoplasmic dynein-1 (hereafter referred to as dynein-1), which is involved in the transport of cargos within the cytoplasm, in organelle dynamics (Reck … WebDynein Axonemal Light Chain 4 (DNAL4) protein is understood to be part of the axonemal (or ciliary and flagellar) complex of dynein molecules (including dynein heavy and light chains) (GO:0005858) and a component of the microtubule-based dynein motor complex [13].In humans, two known axonemal light chain proteins, DNAL1 and DNAL4, sit at the …

WebJul 2, 2024 · Abstract. Dyneins are motor proteins responsible for transport in the cytoplasm and the beating of axonemes in cilia and flagella. They bind and release microtubules via a compact microtubule-binding domain (MTBD) at the end of a coiled-coil stalk. We address how cytoplasmic and axonemal dynein MTBDs bind microtubules at near atomic resolution.

WebProteins are the prime example of self-organized networks, as they have benefited from extensive natural (Darwinian) selection. Here, we quantify the dynamical shapes of dynein as they have evolved through interactions with water films. The interactions are long-range and are easily identified, and their improvement by evolution varies with the ...
