The Sac phosphatase domain
It came to prominence... in 1996 when synaptojanin was cloned and shown to participate with dynamin in synaptic vesicle recycling. Synaptojanin is a phosphatidylinositol 5-phosphatase able to remove the phosphate from the 5-position of phosphatidylinositol(4,5)bisphosphat e (PtdIns(4,5)P2). The Sac domain is a region of homology between the amino terminus of synaptojanin and the otherwise unrel...
متن کاملSac phosphatase domain proteins.
Advances in our understanding of the roles of phosphatidylinositol phosphates in controlling cellular functions such as endocytosis, exocytosis and the actin cytoskeleton have included new insights into the phosphatases that are responsible for the interconversion of these lipids. One of these is an entirely novel class of phosphatase domain found in a number of well characterized proteins. Pro...
متن کاملIdentification and characterization of a sac domain-containing phosphoinositide 5-phosphatase.
We have characterized a novel Sac domain-containing inositol phosphatase, hSac2. It was ubiquitously expressed but especially abundant in the brain, heart, skeletal muscle, and kidney. Unlike other Sac domain-containing proteins, hSac2 protein exhibited 5-phosphatase activity specific for phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 3,4,5-trisphosphate. This is the first time ...
متن کاملThe SAC domain-containing protein gene family in Arabidopsis.
The SAC domain was first identified in the yeast (Saccharomyces cerevisiae) Sac1p phosphoinositide phosphatase protein and subsequently found in a number of proteins from yeast and animals. The SAC domain is approximately 400 amino acids in length and is characterized by seven conserved motifs. The SAC domains of several proteins have been recently demonstrated to possess phosphoinositide phosp...
متن کاملMutation of SAC1, an Arabidopsis SAC domain phosphoinositide phosphatase, causes alterations in cell morphogenesis, cell wall synthesis, and actin organization.
SAC (for suppressor of actin) domain proteins in yeast and animals have been shown to modulate the levels of phosphoinositides, thereby regulating several cellular activities such as signal transduction, actin cytoskeleton organization, and vesicle trafficking. Nine genes encoding SAC domain-containing proteins are present in the Arabidopsis thaliana genome, but their roles in plant cellular fu...
