Disease relevance of SCMH1

 

High impact information on SCMH1

  • Therefore, for the first time, we are able to indicate a functional involvement of Prc1 during the meiotic prophase of male germ cells and a regulatory role of Scmh1 for Prc1, which involves sex chromosomes [2].
  • We have identified the role of Scmh1 in mediating the survival of late pachytene spermatocytes [2].
  • The human homolog of Sex comb on midleg (SCMH1) maps to chromosome 1p34 [3].
  • These data suggest that Scmh1 will have an important role in regulation of homeotic genes in embryogenesis and that the interaction with RAE28/mph1 is important in vivo [1].
  • However, in adults, Scmh1 expression was detected in most tissues, whereas mph1/rae28 expression was restricted to the gonads [1].
 

Biological context of SCMH1

  • Apoptotic elimination of Scmh1(-/-) spermatocytes is accompanied by the preceding failure of several specific chromatin modifications at the XY body, whereas synapsis of homologous autosomes is not affected [2].
 

Other interactions of SCMH1

  • The product of the Scmh1 gene, a mammalian homolog of Drosophila Sex comb on midleg, is a constituent of the mammalian Polycomb repressive complexes 1 (Prc1) [2].
 

Analytical, diagnostic and therapeutic context of SCMH1

  • We analyzed the expression of Scmh1 and rae28/mph1 using northern analysis of embryos and adult tissues, and in situ hybridization to embryos [1].
