The process of directing proteins towards the Golgi using signals contained within the protein.

The regulation of the levels, transport, and metabolism of phosphate ions within a cell or between a cell and its external environment.

The regulation of the levels, transport, and metabolism of chloride ions within a cell or between a cell and its external environment.

Enables the directed movement of organic anions into, out of, within or between cells. Organic anions are atoms or small molecules with a negative charge which contain carbon in covalent linkage.

A multiprotein complex that functions as an antibody. Immunoglobulins (Igs) are composed of two identical heavy chains and two identical light chains, held together by disulfide bonds. The classes of Ig are IgA, IgD, IgE, IgG and IgM; they may be embedded in the plasma membrane or circulate in the blood or lymph.

The formation of a double membrane-bound structure, the autophagosome, that occurs when a specialized membrane sac, called the isolation membrane, starts to enclose a portion of the cytoplasm.

A membrane-bound antigen receptor complex consisting in its basic form of an antigen-binding subunit (the membrane immunoglobulin or mIg), comprised of two identical heavy chains and two identical light chains held together by disulfide bonds, and a signaling subunit, a heterodimer of the Ig-alpha and Ig-beta proteins.

Catalysis of the reaction: hexose(out) = hexose(in).

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.
