General description
Cytoplasmic dynein 1 intermediate chain 1 (UniProt Q29RQ3; also known as Cytoplasmic dynein intermediate chain 1, Dynein intermediate chain 1, cytosolic, DH IC-1) and Cytoplasmic dynein 1 intermediate chain 2 (UniProt Q0III3; also known as Cytoplasmic dynein intermediate chain 2, Dynein intermediate chain 2, cytosolic, DH IC-2) are encoded by the DYNC1I1 gene (Gene ID 613724) and DYNC1I2 gene (Gene ID 526329) in bovine, respectively. Cytoplasmic dynein complexes are microtubules-associated retrograde transport motors. Cytoplasmic dynein 1 is the more abundant motor in cells, while cytoplasmic dynein 2 takes part in intraflagellar transport. Cytoplasmic dynein 1 is a multisubunit complex of ∼1.5 MDa composed of a homodimer of heavy chains (encoded by DYNC1H1), two intermediate chains (encoded by DYNC1I1 and DYNC1I2), light-intermediate chains (encoded by DYNC1LI1, DYNC1LI2) and light chains (encoded by DYNLT1, DYNLT3, DYNLRB1, DYNLRB2, DYNLL1, DYNLLl2). The heavy chain homodimer acts as the dynein complex core and binds microtubules to enable ATP-dependent cytoplasmic dynein movement. The other dynein subunits associate as homodimers and play regulatory roles in maintaining the complex stability, modulating its activity, and mediating its interaction with accessory and cargo proteins. The intermediate chain proteins (IC1 & IC2) are involved in cargo binding and specificity, either alone or via interaction with the dynactin complex. IC1 and IC2 share 69% protein identity. They interact with the dynein light chains and the p150 subunit of dynactin at the N-terminus and with the heavy chains through WD40 repeats at the intermediate chain C-terminus.
Specificity
Not tested on chicken, nematodes or Dictystelium.
Application
Anti-Dynein Antibody, 74 kDa Intermediate chains, cytoplasmic, clone 74.1 detects level of Dynein & has been published & validated for use in IC, IF, IP & WB.
Immunocytochemistry:
1:50-1:100 dilution from a previous lot was used. Reacts with cultured MDCK cells, NRR cells, N1E cells, and PTK-1 cells.
Immunoprecipitation:
10 μL of a previous lot per 0.5 gm tissue was used. The monoclonal cleanly immunoprecipitates the entire dynein complex stoichiometrically from TX-100 or NP-40 lysates (including the 530 kD heavy chain, the light intermediate chains and the light chains) from various tissues and cultured cell lines. If detergents such as SDS are used to prepare the lysates the only dynein subunits which are immunoprecipitated are the IC74 subunits (presumably because the dynein complex dissociates), and other contaminating proteins can be found in SDS immunoprecipitates.
Immunoblotting:
1:1,000-1:5000. Reacts with cultured MDCK cells, PC-12 cells, N1E cells, neurons, glia and other cultured cells.
Optimal working dilutions must be determined by end user.

Cytoplasmic dynein has been implicated in diverse mitotic functions, several involving its association with kinetochores. Much of the supporting evidence comes from inhibition of dynein regulatory factors. To obtain direct insight into kinetochore dynein function, we expressed a series of

The mammalian Golgi ribbon disassembles during mitosis and reforms in both daughter cells after division. Mitotic Golgi membranes concentrate around the spindle poles, suggesting that the spindle may control Golgi partitioning. To test this, cells were induced to divide asymmetrically

Microtubule organization and lysosomal secretion are both critical for the activation and function of osteoclasts, highly specialized polykaryons that are responsible for bone resorption and skeletal homeostasis. Here, we have identified a novel interaction between microtubule regulator LIS1 and Plekhm1

Cytoplasmic dynein is the major microtubule minus-end-directed cellular motor. Most dynein activities require dynactin, but the mechanisms regulating cargo-dependent dynein-dynactin interaction are poorly understood. In this study, we focus on dynein-dynactin recruitment to cargo by the conserved motor adaptor Bicaudal
