The unc-97 gene encodes a LIM domain-containing protein of the PINCH family that is highly similar to human LIMS1 (OMIM:602567) and LIMS2; UNC-97 functions as an adaptor protein important for assembly of muscle adherens junctions and the mechanosensory functions of the touch neurons; UNC-97 interacts with PAT-4/integrin-linked kinase and with UNC-98; UNC-97 colocalizes with PAT-3/beta integrin at dense bodies, focal adhesion-like muscle attachment structures.
Enables myosin binding activity. Involved in several processes, including muscle cell cellular homeostasis; positive regulation of sarcomere organization; and sensory perception of mechanical stimulus. Located in several cellular components, including adherens junction; basal plasma membrane; and contractile fiber. Expressed in body wall musculature and vulval muscle. Human ortholog(s) of this gene implicated in autosomal recessive limb-girdle muscular dystrophy type 2W. Is an ortholog of human LIMS1 (LIM zinc finger domain containing 1) and LIMS2 (LIM zinc finger domain containing 2).
