The elongation of a fatty acid chain by the sequential addition of two-carbon units.

Interacting selectively with Ral protein, any member of the Ral subfamily of the Ras superfamily of monomeric GTPases.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

Organized structure of distinctive morphology and function, not bounded by a lipid bilayer membrane and occurring within the cell. Includes ribosomes, the cytoskeleton and chromosomes.

The volume enclosed by the membranes of a particular organelle, e.g. endoplasmic reticulum lumen, or the space between the two lipid bilayers of a double membrane surrounding an organelle, e.g. nuclear membrane lumen.

Any protein group composed of two or more subunits, which may or may not be identical. Protein complexes may have other associated non-protein prosthetic groups, such as nucleic acids, metal ions or carbohydrate groups.

Catalysis of the hydrolysis of dipeptides Asp-Xaa; does not act on peptides with N-terminal Glu, Asn or Gln, nor does it cleave isoaspartyl peptides.

Any protein group composed of two or more subunits, which may or may not be identical, which undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

Interacting selectively with laminins, glycoproteins that are major constituents of the basement membrane of cells.

Interacting selectively with laminin-1, a glycoprotein trimer with the subunit composition alpha1, beta1, gamma1.

Catalysis of the reaction: CDP + alcohol = CMP + phosphatidyl alcohol.

A change in morphology and behavior of an immune cell resulting from exposure to a specific antigen, mitogen, cytokine, cellular ligand, pathogen, or soluble factor.

Catalysis of the formation of a hydroxyl group on a steroid by incorporation of oxygen from O2.

Catalysis of the reaction: dicarboxylate(out) + Na+(out) = dicarboxylate(in) + Na+(in).
