Comments
  • FUNCTION: Involved in stress resistance and actin organization.
  • SUBUNIT: Interacts with TGFB1I1 (By similarity). Associates with alpha- and beta-tubulin, microtubules and CRYAB. Interacts with HSPB8 and HSPBAP1.

  • SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Cytoplasmic in interphase cells. Colocalizes with mitotic spindles in mitotic cells. Translocates to the nucleus during heat shock.
  • TISSUE SPECIFICITY: Detected in all tissues tested: skeletal muscle, heart, aorta, large intestine, small intestine, stomach, esophagus, bladder, adrenal gland, thyroid, pancreas, testis, adipose tissue, kidney, liver, spleen, cerebral cortex, blood serum and cerebrospinal fluid. Highest levels are found in the heart and in tissues composed of striated and smooth muscle.
  • INDUCTION: Expressed in response to environmental stresses such as heat shock, or estrogen stimulation in MCF-7 cells.
  • PTM: Phosphorylated in MCF-7 cells on exposure to protein kinase C activators and heat shock.
  • DISEASE: Defects in HSPB1 are the cause of Charcot-Marie-Tooth disease type 2F (CMT2F) [MIM:606595]. CMT2F is a form of Charcot-Marie-Tooth disease, the most common inherited disorder of the peripheral nervous system. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathy or CMT1, and primary peripheral axonal neuropathy or CMT2. Neuropathies of the CMT2 group are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. CMT2F onset is between 15 and 25 years with muscle weakness and atrophy usually beginning in feet and legs (peroneal distribution). Upper limb involvement occurs later. CMT2F inheritance is autosomal dominant.
  • DISEASE: Defects in HSPB1 are a cause of distal hereditary motor neuropathy (dHMN) [MIM:608634]. Distal HMN is a pure motor peripheral neuropathy without sensory abnormalities.
  • SIMILARITY: Belongs to the small heat shock protein (HSP20) family.
