Catalysis of an oxidation-reduction (redox) reaction in which an aldehyde or ketone (oxo) group acts as a hydrogen or electron donor and reduces a hydrogen or electron acceptor.

Interacting selectively with DNA containing secondary structure element such as cruciforms.

Catalysis of the phosphorylation of proteins. A family of protein kinases that perform a crucial step in relaying signals from the plasma membrane to the nucleus. Strongly activated by stress signals such as heat or osmotic shock, DNA-damaging agents, inhibitors of protein synthesis and pro-inflammatory cytokines.

The formation from simpler components of C21-steroid hormones, steroid compounds containing 21 carbons which function as hormones.

The directed movement of inorganic anions into, out of, within or between cells. Inorganic anions are atoms or small molecules with a negative charge which do not contain carbon in covalent linkage.

A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome.

The formation from simpler components of androgens, C19 steroid hormones that can stimulate the development of male sexual characteristics.

An immotile primary cilium that may be missing the central pair of microtubules, or the central pair of microtubules and outer dynein arms. Some primary cilia also have altered arrangements of outer microtubules (fewer than nine and/or not always present as doublets). Nonmotile primary cilia typically function as sensory organelles that concentrate and organize sensory signaling molecules.

The formation from simpler components of estrogens, C18 steroid hormones that can stimulate the development of female sexual characteristics. Also found in plants.

The formation of a tri-snRNP complex containing U4 and U6 (or U4atac and U6atac) snRNAs and U5 snRNAs and associated proteins. This includes reannealing of U4 and U6 (or U4atac and U6atac) snRNAs released from previous rounds of splicing to reform the U4/U6 snRNP (or U4atac/U6atac snRNP) as well as the subsequent association of the U5 snRNP with the U4/U6 snRNP (or U4atac/U6atac snRNP) to form a tri-snRNP that is ready to reassemble into another spliceosome complex.
