Gene Name | DACH2 (dachshund family transcription factor 2) |
Location | Xq21.2 |
Dna / Rna | 7 splice transcript variants. |
Protein | 599 amino acids and shorter forms; from N-term to C-term, contains a Poly-Gly (amino acids (aa) 56-61), a Dachshund domain motif N (aa 69-155), which interact with HDAC3 (histone deacetylase 3, 5q31), NCOR1 (nuclear receptor corepressor 1, 17p11.2), and SIX6 (SIX homeobox 6, 14q23.1), a Poly-Ala (aa 350-353), a Dachshund Domain motif C, which interact with EYA2 (eyes absent homolog 2 (Drosophila), 20q13.1), and a Coiled coil domain (aa 459-554) (Swiss-Prot). DACH2 is a transcriptional repressor of MYOG (myogenin, 1q32.1). PAX3 (paired box gene 3, 2q36.1) and DACH2 positively regulate each other, and support the existence of a PAX3/SIX1/EYA2/LBX1/DACH2 network in regulating the myogenic differentiation program (Mennerich and Braun, 2001; Kardon et al., 2002). Histone deacetylase (HDAC4) activity, imported into the nucleus, suppresses DACH2 gene expression in denervated muscle (Tang and Goldman, 2006; Cohen et al., 2007). DACH2 represses SIX1 (SIX homeobox 1, 14q23.1), and SIX1 overexpression has been described in gliomas. DACH1 (13q22) and DACH2 are required for Müllerian duct development. DACH2 is abundantly expressed in fallopian tubes, and it has been implicated in premature ovarian failure syndrome (Bione et al., 2004; Suzumori et al., 2007). In ovarian cancer, DACH2 is expressed, and a significantly reduced overall survival was found for tumours expressing high levels of DACH2 in the subgroup of serous carcinoma, but not in other subgroups (Nodin et al., 2012). |
