actinin a minor protein constituent of muscle, found to be concentrated in both the Z line and the I band. Two components of actinin have been identified: a-actinin, F-actin cross-linking protein, a dimer of ∼200 kDa with an action similar to that of actinogelin.; and b-actinin, a dimer of ∼70 kDa, similar in action to gelsolin.

actin-binding protein any of several proteins that associate with either actin monomers or actin filaments in cells and modify their properties. Many of these proteins are found in the cell cortex, an actin-rich layer just below the plasma membrane. Examples include dystropin, profilin, spectrin and ankyrin, fimbrin and a-actinin (see actinin), filamin, gelsolin, and the myosins. The term is sometimes …
