Figure 4. Chromatin structure and RNA visualization of representative mouse crystallin genes. A: Cryaa (chromosome 17, length of region shown: 40 kb). B: Cryab-Hspb2 (chromosome 9, length of region shown: 20 kb). C: A cluster of six γ-crystallin genes and βA2-crystallin (Cryba2) is present on chromosome 1. A 100 kb region encompassing five genes, including Cryga, Crygb, Crygc, Crygd, and Cryge, is shown. D: Cryba4-Crybb1 (chromosome 5, length of region shown: 40 kb). E) Crybb2-Crybb3 (chromosome 5, length of region shown: 40 kb). Tracks: Lens (FAIRE-seq, pol II, RNA-seq), forebrain (pol II and RNA-seq). Lens epithelium, LEC; lens fiber cells, LFC.
