| description | LIM domain and actin-binding protein 1 (LIMA1, also know as EPLIN) is a cytoskeleton-associated protein that regulates actin dynamics by cross-linking and stabilising filaments []. It was first identified as the product of a gene that is transcriptionally down-regulated or lost in a number of human epithelial tumor cells [, ]. In humans, there are two EPLIN isoforms, EPLIN alpha and EPLIN beta, both have a centrally located LIM domain that may mediate self-dimerisation. EPLIN inhibits Arp2/3 complex-mediated branching nucleation of actin filaments and stabilises actin filament networks []. EPLIN can be regulated through phophoryltion by extracellular signal-regulated kinase (ERK) []. |
