formins
Formins (formin homology proteins) are a group of proteins that are involved in the polymerization of actin and associate with the fast-growing end (barbed end) of actin filaments. Most formins are Rho-GTPase effector proteins. Formins regulate the actin and microtubule cytoskeleton 〔 〕 and are involved in various cellular functions such as cell polarity, cytokinesis, cell migration and SRF transcriptional activity. Formins are multidomain proteins that interact with diverse signalling molecules and cytoskeletal proteins, although some formins have been assigned functions within the nucleus. == Diversity == Formins have been found in all eukaryotes studied.〔 In humans, 15 different formin proteins are present that have been classified in 7 subgroups. By contrast, yeasts contain only 2-3 formins.
