Disease relevance of SFRS10


High impact information on SFRS10

  • Overexpression of RNPS1 in HeLa cells induced exon skipping in a model beta-globin pre-mRNA and a human tra-2 beta pre-mRNA [2].
  • We propose that the regulation of the tra2-beta pre-mRNA alternative splicing provides a robust and sensitive molecular sensor that measures the ratio between HTRA2-BETA1 and its interacting proteins [3].
  • The resulting HTRA2-BETA3 protein lacks the first RS domain of HTRA2-BETA1, is expressed in several tissues and has no influence on tra2-beta splice site selection [3].
  • However, correct splicing can be restored by over-expression of the SR-like splicing factor Htra2-beta 1 [4].
  • We now demonstrate that a second splicing factor, SRp30c, can stimulate SMN exon 7-inclusion and that this activity required the same AG-rich enhancer as hTra2 beta 1 [5].
