CC -!- FUNCTION: Involved in the assembly of dense bodies and M lines during
CC body wall muscle development. Acts by recruiting downstream of
CC integrin-associated protein pat-6/actopaxin several dense bodies and M
CC line components including unc-89, lim-9, scpl-1 and unc-96 to integrin-
CC mediated attachment sites. {ECO:0000269|PubMed:23283987}.
CC -!- SUBUNIT: May interact (via VWFA domain) with unc-89 (via Ig-like C2-
CC type 1-3) and unc-96 (via C-terminus); cpna-1 binding sites for unc-89
CC and unc-96 are different. May interact with pat-6. May interact with
CC lim-9 (via LIM domains) and with scpl-1 (via FCP1 homology domain).
CC {ECO:0000269|PubMed:23283987}.
CC -!- SUBCELLULAR LOCATION: Basal cell membrane
CC {ECO:0000269|PubMed:23283987}; Single-pass type I membrane protein
CC {ECO:0000305}. Cytoplasm, myofibril, sarcomere, M line
CC {ECO:0000269|PubMed:23283987}. Note=Colocalizes with unc-89, unc-112,
CC pat-3 and pat-6 at the M-line and with alpha-actinin, unc-112, pat-3
CC and pat-6 in dense bodies. In body wall muscle cells, colocalizes with
CC beta-integrin pat-3 at integrin adhesion sites.
CC {ECO:0000269|PubMed:23283987}.
CC -!- ALTERNATIVE PRODUCTS:

CC Name=c {ECO:0000312|WormBase:F31D5.3c};
CC IsoId=H2KYS8-3; Sequence=VSP_058734, VSP_058735;
CC -!- TISSUE SPECIFICITY: Expressed in body wall muscles (at protein level).
CC {ECO:0000269|PubMed:23283987}.
CC -!- DEVELOPMENTAL STAGE: Expressed in embryos and in adults.
CC {ECO:0000269|PubMed:23283987}.
CC -!- DISRUPTION PHENOTYPE: Embryos stop elongation at the 2-fold stage and
CC have defects in the organization of the myofibril lattice. pat-3, deb-
CC 1, pat-4 and pat-6 are slightly mislocalized in the post 1.5-fold
CC stage. At the 1.5-fold stage, unc-89 and myo-3 localization is normal.
CC However, at the 1.75- and 2-fold stages, unc-89 and myo-3 are
CC mislocalized into large foci within muscle cells.
CC {ECO:0000269|PubMed:23283987}.
CC -!- SIMILARITY: Belongs to the copine family. {ECO:0000305}.
