...Andrew W. Folkmann; Geraldine Seydoux ABSTRACT The MARK/PAR-1 family of kinases are conserved regulators of cell polarity that share a conserved C-terminal kinase-associated domain (KA1). Localization of MARK/PAR-1 kinases to specific regions of the cell cortex is a hallmark of polarized cells...

... ), a receptor-like cytoplasmic kinase (RLCK) VI family gene, which is ubiquitously detectable in all the tissues examined. RGA activity and GA signaling specifically mediate the levels of STU transcripts in shoot apices that contain actively dividing cells. stu-1 loss-of-function mutants exhibit retarded growth...

... protein kinase II (CamkII, also known as Camk2) activity is upregulated prior to hypertrophy and that loss of CamkII function substantially blocks the transition from proliferation to hypertrophy. Wnt signaling and Pthrp-induced phosphatase activity negatively regulate CamkII activity. Release...

...Ken-ichi Ogura; Yoshio Goshima UNC-51 and UNC-14 are required for the axon guidance of many neurons in Caenorhabditis elegans . UNC-51 is a serine/threonine kinase homologous to yeast Atg1, which is required for autophagy. The binding partner of UNC-51, UNC-14, contains a RUN domain...

... tissues by reorganizing the cytoskeleton. The selection of different molecular targets in the pathway is driven by multiple phosphorylation events. Here, we report that metastasis-associated kinase (MAK) is a novel regulator of Wnt signaling during morphogenetic movements, and eye and brain development...

... tyrosine kinase torso at the posterior egg pole triggers a signal transduction pathway. This pathway, mediated through the serine/threonine protein kinase D-raf and the protein tyrosine phosphatase corkscrew , controls the domains of expression of the transcription factors tailless and huckebein...
