a small heat shock protein that is regulated both transcriptionally and posttranslationally. Modulates actin polymerization and reorganization. Its expression level increases several-fold in response to stress and is phosphorylated by MAPKAP kinase 2. Cytoplasmic in interphase cells. Colocalizes with mitotic spindles in mitotic cells. Translocates to the nucleus during heat shock. Note: This description may include information from UniProtKB.
