Structured_descriptionConcise_descriptionmbk-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 oocyte-to-egg 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) post-fertilization 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; MBK-2 also primes the MEX-5 polarity protein for subsequent phosphorylation by the polo-like kinase PLK-1; 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 and MEX proteins; MBK-2 activity depends upon progression through the meiotic divisions and is positively regulated by CDK-1 and negatively regulated by EGG-3 and EGG-4/5; MBK-2 physically interacts with EGG-3 and EGG-4, suggesting that regulation by EGG-3 and EGG-4 is direct; MBK-2 is expressed uniformly in the cortex of oocytes and newly fertilized zygotes; in later stage 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.Paper_evidenceWBPaper00006085

Automated_descriptionEnables protein serine/threonine kinase activity and protein tyrosine kinase activity. Involved in several processes, including P granule disassembly; asymmetric protein localization involved in cell fate determination; and positive regulation of proteasomal ubiquitin-dependent protein catabolic process. Located in cell cortex and intracellular non-membrane-bounded organelle. Expressed in several structures, including body wall musculature; embryonic cell; gonad; oocyte; and pharynx. Used to study Down syndrome. Is an ortholog of human DYRK2 (dual specificity tyrosine phosphorylation regulated kinase 2) and DYRK3 (dual specificity tyrosine phosphorylation regulated kinase 3).Paper_evidenceWBPaper00065943

Disease_relevanceHuman DYRK1A gene encodes a member of the dual-specificity tyrosine phosphorylation-regulated kinase (DYRK) family, which includes Drosophila minibrain, and is a conserved gene located in the Down Syndrome critical region (DSCR) of chromosome 21; Down syndrome is the most frequent chromosomal abnormality in human infants, where DYRK1A overexpression is observed, and is characterized by a set of facial and physical features, heart defects, abnormalities in the immune and endocrine systems, spatial memory defecits and difficulty in converting short-term to long-term memories; in elegans, the genes mbk-1 and mbk-2 have close homology with human DYRK1A and hpk-1 is more distantly related; while mutants deficient for mbk-1 seem to be normal, overexpression of mbk-1 causes behavioral defects in chemotaxis, acting in mature, fully differentiated neurons; however, this defect could be reversed by bringing back normal mbk-1 levels, which provided the first hint that DYRK1-induced defects could be reversed; mbk-2(pk1427) homozygous animals display 100% penetrant maternal-effect embryonic lethality, making it difficult to test redundant function with mbk-1.Homo sapiensPaper_evidenceWBPaper00005756

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.CGC_data_submission
