CC   -!- FUNCTION: Required for oocyte-to-zygote transition in which it
CC       phosphorylates oocyte proteins, including mei-1, oma-1, oma-2, mex-5,
CC       and mex-6, modifying their activity and/or stability following meiosis
CC       (PubMed:16289132, PubMed:16338136, PubMed:17869113, PubMed:18854162,
CC       PubMed:18199581, PubMed:19879842). Through phosphorylation of P granule
CC       components including meg-1, promotes the disassembly of zygotic P
CC       granules in the anterior cytoplasm during zygote polarization, and thus
CC       plays a role in P granule distribution and segregation in early stage
CC       embryos following meiosis (PubMed:25535836). Functions in both spindle
CC       positioning and in the posterior localization of cytoplasmic
CC       determinants, including pie-1, pos-1, and pgl-1, in early embryos
CC       (PubMed:14697358). Involved in the asymmetric distribution of plk-1 at
CC       the 2-cell embryonic stage (PubMed:18199581).

CC   -!- ACTIVITY REGULATION: Activated during oocyte maturation by
CC       phosphorylation on Ser-362 by cdk-1. The pseudotyrosine phosphatases
CC       egg-4 and egg-5 sequester activated mbk-2 until the meiotic divisions
CC       and inhibit mbk-2 kinase activity directly, using a mixed-inhibition
CC       mechanism that does not involve tyrosine dephosphorylation.

CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:

CC         Note=The presence of egg-4 in the assay increases the KM of mbk-2 for
CC         mei-1. {ECO:0000269|PubMed:19879842};
CC   -!- SUBUNIT: Part of a complex, consisting of pseudophosphatases egg-3,
CC       egg-4, egg-5 and kinase mbk-2; this complex is required for the oocyte-
CC       to-zygote transition (PubMed:19879842). Interacts (via Tyr-619 and Tyr-
CC       621) with egg-4 (via tyrosine-protein phosphatase domain) and egg-5
CC       (via tyrosine-protein phosphatase domain); mbk-2 tyrosine
CC       phosphorylation enhances the interaction (PubMed:19879842). The
CC       interaction inhibits mbk-2 kinase activity and is required for mbk-2
CC       oocyte cortex localization. Interacts (via N-terminus) with egg-3 (via
CC       tyrosine-protein phosphatase domain); the interaction does not affect
CC       mbk-2 kinase activity, is enhanced by mbk-2 tyrosine phosphorylation
CC       status and requires prior binding of mbk-2 to egg-4 and egg-5
CC       (PubMed:17869113, PubMed:19879842). {ECO:0000269|PubMed:17869113,

CC       Note=Maintained at the cortex by the cortical anchor egg-3 before
CC       meiotic divisions. During anaphase of meiosis I, egg-3 translocates
CC       into the cytoplasm on vesicles and is slowly degraded, releasing mbk-2.

CC   -!- TISSUE SPECIFICITY: In L1 larvae, expressed widely in the nervous
CC       system, including head neurons and the ventral nerve cord. In adult
CC       animals, continues to be expressed in the nervous system and is also
CC       expressed in body wall muscle. {ECO:0000269|PubMed:12618396}.
CC   -!- DEVELOPMENTAL STAGE: Expressed both maternally and zygotically.
CC       {ECO:0000269|PubMed:12618396}.
CC   -!- PTM: Autophosphorylated. {ECO:0000269|PubMed:19879842}.
CC   -!- DISRUPTION PHENOTYPE: Maternal-effect embryonic lethality due to
CC       defects in spindle positioning and cytokinesis in the early embryo
CC       (PubMed:12618396, PubMed:14697358). Microtubules are fragmented and
CC       disordered (PubMed:14697358). Abolishes phosphorylation of RNA-binding
CC       protein oma-1 in embryos (PubMed:16289132). RNAi-mediated knockdown
CC       causes an increase in taf-4 nuclear localization in the one-cell embryo
CC       (PubMed:18854162). RNAi-mediated knockdown causes a loss in plk-1
CC       asymmetric localization in 2-cell stage embryo without affecting mex-5
CC       polarization (PubMed:18199581). RNAi-mediated knockdown disrupts P
CC       granule distribution in zygotes after meiosis whereby zygotic P
CC       granules fail to disassemble in the anterior cytoplasm during zygote
CC       polarization, however new P granules assemble and accumulate in the
CC       posterior cytoplasm as in wild-type (PubMed:25535836).
