WebOct 20, 2024 · In this study, we constituted actin–cofilin rods using purified actin, cofilin and actin interacting protein 1 (AIP1) in the presence of a physiological buffer containing a crowding agent, 0.8% methylcellulose (MC), which led to bundled actin filaments formed by depletion forces.
WebEarly studies examining rod-like cofilin aggregates in primary neurons demonstrated 12E8 antibody immunoreactivity in a subset of cofilin-positive rods resembling neuropil threads. The 12E8 antibody recognizes the pSer262/pSer356 of tau and other phosphorylated MAPs, suggesting that cofilin might coprecipitate together with tau and/or other ... WebThe rod domains of two neurofilament proteins dimerize to form an alpha-helical coiled coil. Two dimers associate in a staggered antiparallel manner to form a tetramer. This tetramer is believed to be the basic subunit (i.e. building block) of the neurofilament. Tetramer subunits associate side-to-side to form unit-length filaments, which then ...
