HSPB1 Antibody – Mouse Monoclonal

The protein encoded by this gene is induced by environmental stress and developmental changes. The encoded protein is involved in stress resistance and actin organization and translocates from the cytoplasm to the nucleus upon stress induction. Defects in this gene are a cause of Charcot-Marie-Tooth disease type 2F (CMT2F) and distal hereditary motor neuropathy (dHMN). [provided by RefSeq, Oct 2008]

HSP27: 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.
