Plectin-1 (human)

Overview
Plectin-1 a major cytoskeleton crosslinking protein that binds to actin, intermediate filaments and microtubules. A scaffold for proteins involved in cellular signaling. Interlinks intermediate filaments with microtubules and microfilaments and anchors intermediate filaments to desmosomes or hemidesmosomes. Could also bind muscle proteins such as actin to membrane complexes in muscle. May be involved not only in the cross-linking and stabilization of cytoskeletal intermediate filaments network, but also in the regulation of their dynamics. Regulates the organization of keratin intermediate filaments (IF) and MAPK signaling during cell migration. Downregulates PKC signaling by sequestering RACK1. Redistributes to the uropod associated with vimentin and fodrin during polarization of peripheral blood T lymphocytes. This vimentin-plectin-fodrin complex provides a continuous linkage from the nucleus (lamin B) to the cortical cytoskeleton. Defects in PLEC1 are the cause of epidermolysis bullosa simplex 1 (EBS1). Three alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
