Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Protein inferred from homologyi <p>This indicates the type of evidence that supports the existence of the protein. Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Required for oocyte-to-zygote transition in which it phosphorylates oocyte proteins, including mei-1, oma-1, oma-2, mex-5, and mex-6, modifying their activity and/or stability following meiosis. Functions in both spindle positioning and in the posterior localization of cytoplasmic determinants, including pie-1, pos-1, and pgl-1, in early embryos. Involved in the asymmetric distribution of plk-1 at the 2-cell embryonic stage.By similarity

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori

Activated during oocyte maturation by phosphorylation on Ser-361 by cdk-1. The pseudotyrosine phosphatases egg-4 and egg-5 sequester activated mbk-2 until the meiotic divisions and inhibit mbk-2 kinase activity directly, using a mixed-inhibition mechanism that does not involve tyrosine dephosphorylation (By similarity).By similarity

Part of a complex, consisting of pseudophosphatases egg-3, egg-4, egg-5 and kinase mbk-2.

Interacts (via Tyr-618 and Tyr-620) with egg-4 (via tyrosine-protein phosphatase domain) and egg-5 (via tyrosine-protein phosphatase domain); mbk-2 tyrosine phosphorylation enhances the interaction. The interaction inhibits mbk-2 kinase activity and is required for mbk-2 oocyte cortex localization.

Interacts (via N-terminus) with egg-3 (via tyrosine-protein phosphatase domain); the interaction does not affect mbk-2 kinase activity, is enhanced by mbk-2 tyrosine phosphorylation status and requires prior binding of mbk-2 to egg-4 and egg-5.
