Gene Inhibited  F49E11.1 (mbk-2)
Description of "F49E11.1"  mbk-2 encodes one of two C. elegans members of the DYRK (dual-specificity Yak1-related kinase) family of proteins that includes S. cerevisiae Yak1 and the Drosophila minibrain and DYRK2 kinases; MBK-2 activity is required maternally for the egg-to-embryo transition that occurs during the earliest stages of embryonic development; specifically, MBK-2 is required for: 1) posterior localization of the germ plasm components PIE-1, POS-1, and PGL-1, and 2) postfertilization degradation of a subset of maternal proteins including the MEI-1 and MEI-2 meiosis-specific katanin subunits, the OMA-1 oocyte maturation factor, and residual PIE-1 that remains anteriorly localized after its normal posterior segregation; genetic analyses suggest that, in regulating the segregation and degradation of maternal proteins, mbk-2 lies downstream of the initial embryonic polarity cues established by the PAR/MEX proteins; MBK-2, whose activity appears to depend upon progression through the meiotic divisions, is expressed uniformly in the cortex of oocytes and newly fertilized zygotes; in later zygotes, just prior to the second meiotic division, MBK-2 becomes localized to discrete cortical foci, and by the first mitosis it is found predominantly on centrosomes and chromosomes; MBK-2 is also associated with P granules in the germline blastomeres P2, P3, and P4.
