OTHER CONVENTIONAL PROTEIN KINASE DOMAIN KINASES -
The group of 'other conventional protein kinase domain kinases' consists of kinases with a conventional eukaryotic protein kinase domain that do not fit into any of the other major groups. This grouping is described in FBrf0201870.
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
ald: altered disjunction (A.T.C. Carpenter)
Homozygous females display elevated levels of non-disjunction of X and fourth chromosomes (9.5 and 6.0% respectively); double exceptions are predominantly XX;0 and 0;44, products expected from nonhomologous disjunction; behavior of large autosomes nearly normal. Exchange frequencies normal, and sex-chromosome exchange tetrads contribute to exceptional products.

      Additional comments
      The gene symbol "ald" has been changed to "Mps1" to reflect published usage and in order to reduce confusion with the "Ald" ("Aldolase") gene symbol, from which it differed only by case.
      Other Comments
      The rate of meiotic errors in ald mutant females is linked to an increased likelihood of premature release of sister chromatid cohesion, rather than just a shortening of prometaphase duration.
      dsRNA against this gene has been used to treat SL2 cells to study the effect of depletion of ald on the spindle checkpoint.
      CG31251- CG31360+ CG31249- Overall orientation not stated: CG14322+ CG7523- ald+ CG18212- CG7655+
      Cytological analysis shows that ald plays a role in the maintenance of the chiasmate homolog associations during meiotic metaphase I.
      When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, decrease in mitotic index, a decrease in the ratio of cells in prometaphase and metaphase versus the total number of mitotic cells and spindle abnormalities are seen.
      RNAi experiments in S2 cells causes no discernable phenotype. Over-expression results in cells displaying abnormal anaphases, with chromatin stretched over the central spindle.
      ald is required for the mitotic spindle checkpoint and is required for the metaphase arrest that results in response to hypoxic conditions.
      dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
      ald kinase plays a role in centrosome duplication and the mitotic spindle checkpoint.
      Mutant females show an increased frequency of nondisjunction of the X and 4th chromosomes.
