The set of genes down-regulated in
gei-8 mutants included several genes required for proper muscle function, including
unc-52 (myofilament assembly and/or attachment of the myofilament lattice to the cell membrane),
unc-27 (troponin I family),
unc-54 (muscle myosin class II heavy chain),
pat-10 (body wall muscle troponin C),
lev-11 (tropomyosin),
mlc-2 (myosin light-chain), and
tni-1 (troponin 1).
