Catalysis of the reaction: ATP + sphinganine = ADP + sphinganine 1-phosphate.

A voltage-gated proton channel; unique among ion channels with respect to their extremely high selectivity, marked temperature dependence, and unitary conductance, which is three orders of magnitude lower than that of most ion channels.

Catalysis of the reaction: SO3(2-) (sulfite) + O2 + H2O = SO4(2-) (sulfate) + H2O2.

Interacting selectively with troponin C, the calcium-binding subunit of the troponin complex.

Catalysis of the transfer of an amino group to an acceptor, usually a 2-oxo acid.

Penetrating at least one phospholipid bilayer of the Golgi complex membrane. Also refers to the state of being buried in the bilayer with no exposure outside the bilayer.

Catalysis of the reaction: RSO-R' + H2O = RSOOH + R'H. This reaction is the hydrolysis of any sulfuric ester bond, any ester formed from sulfuric acid, O=SO(OH)2.

regulation of DNA replication initiation

Any process that modulates the frequency, rate or extent of initiation of DNA replication; the process by which DNA becomes competent to replicate. In eukaryotes, replication competence is established in early G1 and lost during the ensuing S phase.

Thin, stiff protrusion extended by the leading edge of a motile cell such as a crawling fibroblast or amoeba, or an axonal growth cone; usually approximately 0.1 um wide, 5-10 um long, can be up to 50 um long in axon growth cones; contains a loose bundle of about 20 actin filaments oriented with their plus ends pointing outward.

Catalysis of the reaction: (-)-limonene + NADPH + H+ + O2 = (-)-perillyl alcohol + NADP+ + H2O.

Catalysis of the reaction: diphospho-myo-inositol polyphosphate + H2O = myo-inositol polyphosphate + phosphate.

integral to endoplasmic reticulum membrane

Penetrating at least one phospholipid bilayer of an endoplasmic reticulum membrane. Also refers to the state of being buried in the bilayer with no exposure outside the bilayer.

The assembly and arrangement of cytoskeletal structures.
