Phosphatidylinositol monophosphate 5-kinase (PIP5K) catalyzes the synthesis of PI-4,5-bisphosphate (PtdIns(4,5)P(2)) by phosphorylation of PI-4-phosphate at the 5 position of the inositol ring, and is involved in regulating multiple developmental processes and stress responses. We here report on the functional characterization

Multiple repeats of membrane occupation and recognition nexus (MORN) motifs were detected in plant phosphatidylinositl monophosphate kinase (PIPK), a key enzyme in PI-signaling pathway. Structural analysis indicates that all the MORN motifs (with varied numbers at ranges of 7-9), which

Inward rectifier K+ channels, which modulate electrical activity in many cell types, are regulated by protein kinases, guanine-nucleotide-binding proteins (G proteins) and probably actin cytoskeleton. Generation of phosphatidylinositol 4,5-bisphosphate (PIP2) by ATP-dependent lipid kinases is known to activate inward rectifier

The pleckstrin homology (PH) domain is an approximately 100-amino-acid region of sequence homology present in numerous proteins of diverse functions, which forms a discrete structural module. Several ligands capable of binding to PH domain-containing proteins have been identified including phosphatidylinositol
J E Harlan et al.
Biochemistry, 34(31), 9859-9864 (1995-08-08)
The pleckstrin homology (PH) domain is a protein module of approximately 100 amino acids that is found in several proteins involved in signal transduction [for a recent review, see Gibson et al. (1994) Trends Biochem. Sci. 19, 349-353]. Although the
