Enables the directed movement of folic acid (pteroylglutamic acid) into, out of, within or between cells. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines.

A membrane-bound, cytoplasmic secretory granule found in enzyme-secreting cells and visible by light microscopy. Contain zymogen, an inactive enzyme precursor, often of a digestive enzyme.

Interacting selectively with transfer RNA.

The outer membrane of a zymogen granule.

Enables the directed movement of ammonium into, out of, within or between cells. Ammonium is the cation NH4+ which is formed from N2 by root-nodule bacteria in leguminous plants and is an excretory product in ammonotelic animals.

regulation of mitochondrial membrane permeability

regulation of transport across mitochondrial membrane

Any process that modulates the frequency, rate or extent of the passage or uptake of molecules by the mitochondrial membrane.

The regulated release of a substance by a cell or group of cells.

Interacting selectively with calcium oxalate, CaC2O4, a salt of oxalic acid. In animals, it may be excreted in urine or retained in the form of urinary calculi.

Interacting selectively with a tetrapyrrole, a compound containing four pyrrole nuclei variously substituted and linked to each other through carbons at the alpha position.

The directed movement of substances within a cell.

Catalysis of the transfer of a mannosyl group to an acceptor molecule, typically another carbohydrate or a lipid.

Interacting selectively with any isoprenoid compound, isoprene (2-methylbuta-1,3-diene) or compounds containing or derived from linked isoprene (3-methyl-2-butenylene) residues.

Any process that modulates the frequency, rate or extent of cell killing.

Interacting selectively with retinol, vitamin A1, 2,6,6-trimethyl-1-(9'-hydroxy-3',7'-dimethylnona-1',3',5',7'-tetraenyl)cyclohex-1-ene, one of the three components that makes up vitamin A. Retinol is an intermediate in the vision cycle and it also plays a role in growth and differentiation.
