Enigma/PDLIM1 [MD100]

PDLIM1 (PDZ and LIM domain 1), also known as Enigma, CLIM1, CLP36, or Elfin, is a 329 amino acid cytoplasmic protein that associates with actin stress fibers at the cytoskeleton. This gene encodes a member of the enigma protein family. The protein contains two protein interacting domains, a PDZ domain at the amino terminal end and one to three LIM domains at the carboxyl terminal. It is a cytoplasmic protein associated with the cytoskeleton. Expressed at high levels in skeletal muscle and heart and at lower levels in colon, small intestine, spleen, lung, placenta, kidney, liver, thymus and pancreas, especially PDLIM1 functions as a cytoskeletal protein that is thought to act as an adaptor, bringing target proteins to the cytoskeleton. The protein has a role in cell migration, invasion and metastasis in breast cancer.
