function:Serves as an anchoring site for cell-ECM adhesion proteins and filamin-containing actin filaments. Is implicated in cell shape modulation (spreading) and motility. May participate in the regulation of filamin-mediated cross-linking and stabilization of actin filaments. May also regulate the assembly of filamin-containing signaling complexes that control actin assembly.,similarity:Contains 3 LIM zinc-binding domains.,subcellular location:Associated with actin stress fiber at cell-ECM focal adhesion sites. Isoform 1 and isoform 3 are recruited and localized at actin stress fibers and clustered at cell-EMC adhesion sites through interaction with PLEKHC1. Isoform 2 is localized at actin stress fibers.,subunit:Isoform 1 and isoform 3 interact with PLEKHC1, FLNA and FLNC. Isoform 2 interacts with FLNB. Interacts with NKX2-5.,tissue specificity:Isoform 1 and isoform 3 are expressed in heart, kidney, lung, pancreas, placenta and platelets. Isoform 2 is expressed in brain, heart, kidney, lung, pancreas, placenta, skeletal muscle and platelets.,
Cell junction, focal adhesion . Cytoplasm, cytoskeleton, stress fiber . Associated with actin stress fiber at cell-ECM focal adhesion sites (PubMed:12679033, PubMed:18829455). Isoform 1 and isoform 3 are recruited and localized at actin stress fibers and clustered at cell-EMC adhesion sites through interaction with FERMT2 (PubMed:12679033).
