UniProtKB - Q9UPQ0 (LIMC1_HUMAN)
Protein
LIM and calponin homology domains-containing protein 1
Gene
LIMCH1
Organism
Homo sapiens (Human)
Status
Functioni
Actin stress fibers-associated protein that activates non-muscle myosin IIa. Activates the non-muscle myosin IIa complex by promoting the phosphorylation of its regulatory subunit MRLC/MYL9. Through the activation of non-muscle myosin IIa, positively regulates actin stress fibers assembly and stabilizes focal adhesions. It therefore negatively regulates cell spreading and cell migration.1 Publication
