..We propose that MBK-2 functions as a temporal regulator of protein stability, and that coordinate activation of maternal protein degradation is one of the mechanisms that drives the transition from symmetric egg to patterned embryo. ..

..We propose that mbk-2 potentiates the degradation of MEI-1 and other proteins, possibly via direct phosphorylation. ..

..Our results suggest that increased gene dosage of human DYRK1A in trisomy 21 may disrupt the function of fully differentiated neurons and that this disruption is reversible. ..

. The minibrain kinase homolog, mbk-2, is required for spindle positioning and asymmetric cell division in early C. elegans embryos. Dev Biol. 2004;265:127-39 pubmed
..These findings in conjunction with work from Schizosaccharomyces pombe indicate a possible conserved role for Dyrk family kinases in the regulation of spindle placement during cell division. ..
