Costars

Costars
SMART accession number:SM01283
Description: This domain is found both alone and at the C-terminus of actin-binding Rho-activating protein (ABRA). It binds to actin, and in muscle regulates the actin cytoskeleton and cell motility PMID:11983702, 20940261. It has a winged helix-like fold consisting of three alpha-helices and four antiparallel beta strands. Unlike typical winged helix proteins it does not bind to DNA, but contains a hydrophobic groove which may be responsible for interaction with other proteins PMID:21082705 .
