HSPB1

HSPB1

A gene on chromosome 7q11.23 that encodes a member of the (small) heat shock protein 20 family which is induced by environmental stress. HSPB1 plays a role in stress resistance and actin organisation; it translocates from the cytoplasm to the nucleus in response to stress. It associates with alpha- and beta-tubulin, microtubules and CRYAB, and interacts with HSPB8 and HSPBAP1.

Molecular pathology
Defects of HSPB1 cause Charcot-Marie-Tooth disease type 2F and distal hereditary motor neuropathy 2B.

We performed functional gene set enrichment analysis on genes containing DMS using the DAVID web server and found that many of the 47 differentially methylated genes are related to important biological functions of cancer, for example, regulation of apoptosis and programmed cell death with RTN4, NME2, CASP14, HSPB1, RPL11, and RPS3 differentially methylated (Excel Sheet S1).
