A process leading to shortening and/or development of tension in smooth muscle tissue.

Interacting selectively with retinoids, any member of a class of isoprenoids that contain or are derived from four prenyl groups linked head-to-tail. Retinoids include retinol and retinal and structurally similar natural derivatives or synthetic compounds, but need not have vitamin A activity.

Catalysis of the reaction: AMP + diphosphate = adenine + 5-phospho-alpha-D-ribose 1-diphosphate.

The complete fully infectious extracellular virus particle.

Interacting selectively with fatty acids, aliphatic monocarboxylic acids liberated from naturally occurring fats and oils by hydrolysis.

Catalysis of the reaction: L-2-aminoadipate + 2-oxoglutarate = 2-oxoadipate + L-glutamate.

Interacting selectively with iron (Fe) ions.

Interacting selectively with copper (Cu) ions.

maintenance of apical/basal cell polarity

Retaining the established polarization of a cell along its apical/basal axis.

Destruction of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.

Interacting selectively with any inositol-containing glycerophospholipid.

Interacting selectively with calcium ions (Ca2+).

Interacting selectively with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.

A multimeric complex that is able to catalyze the addition of methyl groups to histone proteins.

Interacting selectively with cations, charged atoms or groups of atoms with a net positive charge.

The molecular events that lead to the integration of a viral genome into the host genome.

Interactions, directly with the host cell macromolecular machinery, to allow virus replication.

negative regulation of caspase activation

Any process that stops, prevents or reduces the rate of caspase activation.

A structural framework, or 'dense core' at the interior of an acrosome. May regulate the distribution of hydrolases within the acrosome and their release during the acrosome reaction.
