Structural and thermodynamic characterization of a cytoplasmic dynein light chain-intermediate chain complex.
Cytoplasmic dynein is a microtubule-based motor protein complex that plays important roles in a wide range of fundamental cellular processes, including vesicular transport, mitosis, and cell migration. A single major form of cytoplasmic dynein associates with membranous organelles, mitotic kinetochores, the mitotic and migratory cell cortex, centrosomes, and mRNA complexes. The ability of cytop...
متن کاملCharacterization of cytoplasmic dynein light-intermediate chain isoforms in rat testis.
We obtained three kinds of novel cytoplasmic dynein light-intermediate chain (LIC) isoforms from rat testis and brain by reverse transcription polymerase chain reaction (RT-PCR). The primers for RT-PCR were designed according to LIC-2 (LIC 53/55) (15). In one novel isoform, the 42 bp specific sequence named TDL was inserted between 1,106 and 1,107 nucleotides (nts) of LIC-2, whereas the 57 bp s...
متن کاملLight chain-dependent self-association of dynein intermediate chain.
Dynein light chains are bivalent dimers that bind two copies of dynein intermediate chain IC to form a cargo attachment subcomplex. The interaction of light chain LC8 with the natively disordered N-terminal domain of IC induces helix formation at distant IC sites in or near a region predicted to form a coiled-coil. This fostered the hypothesis that LC8 binding promotes IC self-association to fo...
متن کاملMolecular analysis of a cytoplasmic dynein light intermediate chain reveals homology to a family of ATPases.
Cytoplasmic dynein is a multi-subunit complex involved in retrograde organelle transport and some aspects of mitosis. In previous work we have cloned and sequenced cDNAs encoding the rat cytoplasmic dynein heavy and intermediate chains. Here we report the cloning of the remaining class of cytoplasmic dynein subunits, which we refer to as the light intermediate chains (LICs: 53-59 kDa). Four LIC...
متن کاملBehavioral and other phenotypes in a cytoplasmic Dynein light intermediate chain 1 mutant mouse.
The cytoplasmic dynein complex is fundamentally important to all eukaryotic cells for transporting a variety of essential cargoes along microtubules within the cell. This complex also plays more specialized roles in neurons. The complex consists of 11 types of protein that interact with each other and with external adaptors, regulators and cargoes. Despite the importance of the cytoplasmic dyne...
