Actin molecules in a dual-stranded helical polymer. Together with the tropomyosin-tropinin regulatory complex, F-actin constitutes the thin filaments of skeletal muscle.
f allotype
A rabbit immunoglobulin A (IgA) subclass
α
heavy-chain allotype. Allelic genes at the
f
locus encode five
f
allotypes. These are designated f69 through f73. More than one allotypic determinant is associated with each allotype.
