Abstract

The role of multifunctional Ca2+/calmodulin-dependent protein kinase (CaM kinase) in nuclear envelope breakdown (NEB) was investigated in sea urchin eggs. The eggs contain a 56-kD polypeptide which appears to be a homologue of neuronal CaM kinase. For example, it undergoes Ca2+/calmodulin-dependent autophosphorylation that converts it to a Ca2(+)-independent species, a hallmark of multifunctional CaM kinase. It is homologous to the alpha subunit of rat brain CaM kinase. Autophosphorylation and substrate phosphorylation by the sea urchin egg kinase are inhibited in vitro by CaMK(273-302), a synthetic peptide corresponding to the autoinhibitory domain of the neuronal CaM kinase. This peptide inhibited NEB when microinjected into sea urchin eggs. Only one mAb to the neuronal enzyme immunoprecipitated the 56-kD polypeptide. Only this antibody blocked or significantly delayed NEB when microinjected into sea urchin eggs. These results suggest that sea urchin eggs contain multifunctional CaM kinase, and that this enzyme is involved in the control of NEB during mitotic division.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
