HSPB8 - heat shock protein family B (small) member 8 Gene
Also Known as H11; HMN2; CMT2L; DHMN2; E2IG1; HMN2A; HSP22
Species: Homo sapiens
About HSPB8
This gene has 14 transcripts (splice variants), 219 orthologues, 8 paralogues and is associated with 5 phenotypes. Broad expression in heart (RPKM 181.8), esophagus (RPKM 96.6) and 15 other tissues.
Summary
The protein encoded by this gene belongs to the superfamily of small heat-shock proteins containing a conservative alpha-crystallin domain at the C-terminal part of the molecule. The expression of this gene in induced by estrogen in estrogen receptor-positive breast Cancer cells, and this protein also functions as a chaperone in association with Bag3, a stimulator of macroautophagy. Thus, this gene appears to be involved in regulation of cell proliferation, Apoptosis, and carcinogenesis, and mutations in this gene have been associated with different neuromuscular diseases, including Charcot-Marie-Tooth disease.
