WebJan 1, 2001 · The major phenotype in these mice, lacking both αB-crystallin and small heat shock protein HSPB2 (encoded by an adjacent gene that was also disrupted), is a progressive muscular dystrophy that destroys a specific subset of skeletal muscles, particularly those in the head and perivertebral regions. WebJan 16, 2024 · Proteomics analysis of 2-day-old DKO and Cryaa -R49C knock-in mouse lenses revealed an increased abundance of histones H2A, H2B fragment, and H4. Furthermore, we discovered that the mutant αA-R49C protein is distributed mainly in the nucleus of the lens, where this protein may bind and sequester histones [ 7 ].
