WebMar 28, 2024 · But, HMMR is an intracellular, microtubule-associated, spindle assembly factor that localizes protein complexes to augment the activities of mitotic kinases, like polo-like kinase 1 and Aurora kinase A, and control dynein and kinesin motor activities. Expression of HMMR is elevated in cells prior to and during mitosis and tissues with ... WebMar 4, 2012 · Abstract. Primary ciliary dyskinesia most often arises from loss of the dynein motors that power ciliary beating. Here we show that DNAAF3 (also known as PF22), a previously uncharacterized protein, is essential for the preassembly of dyneins into complexes before their transport into cilia. We identified loss-of-function mutations in the …

WebRemoval of the centrosomal protein 110 (CP110) from the distal end of the mother centriole initiates the ciliary assembly. The work from Lee et al. demonstrated the differential role of the DAP, sodium channel and clathrin linker 1 (Sclt1) in ciliogenesis during embryonic fore- and hindlimb development in novel Sclt1 mutant mice. Sclt1 ... WebJul 15, 2024 · A wdr92-1 tpg1-2 double mutant builds ∼7-μm immotile flaccid cilia that completely lack dynein arms. These data indicate that WDR92 is a key assembly factor specifically required for the stability of axonemal dynein heavy chains in cytoplasm and suggest that cytoplasmic/IFT dynein heavy chains use a distinct folding pathway.
WebCLIP-170 is a plus-end tracking protein which may act as an anticatastrophe factor. It has been proposed to mediate the association of dynein/dynactin to microtubule (MT) plus ends, and it also binds to kinetochores in a dynein/dynactin-dependent fashion, both via its C-terminal domain. WebFigure 1. SPDL-1 is a transient kinetochore component essential for chromosome segregation.
