F-Actin

Filamentous actin (F-actin) is also referred to as microfilament [1] and is a highly conserved proteinous component found near ubiquitously in eukaryotic cytoskeletons. F-actin and other actin proteins generally provide a structural role to the cell.

History

The F-actin structure was discovered by Straub in 1942. The structure was speculated based on a low-resolution x-ray crystallograph found in 1990 by Holmes et al. The structure was deposited in the PDB databank in Decemeber 2008 by Oda et al. [2].
