The linkage of cytochromes and other heme proteins to heme.

The covalent linking of a cofactor to a protein.

Any activity required to initiate or regulate transcription; includes the actions of both gene regulatory proteins as well as the general transcription factors.

RNA polymerase I transcription factor activity

Functions to initiate or regulate RNA polymerase I transcription.

RNA polymerase II transcription factor activity

Functions to initiate or regulate RNA polymerase II transcription.

specific RNA polymerase II transcription factor activity

Functions to enable the transcription of specific, or specific sets, of genes by RNA polymerase II.

RNA polymerase II transcription factor activity, enhancer binding

Functions to initiate or regulate RNA polymerase II transcription by binding a promoter or enhancer region of DNA.

Combining with a steroid hormone to initiate a change in cell activity.

Combining with retinoic acid to initiate a change in cell activity. Retinoic acid is one of the forms of vitamin A.

RNA polymerase III transcription factor activity

Functions to initiate or regulate RNA polymerase III transcription.

The assembly and arrangement of the nucleolus.

chromosome organization and biogenesis (sensu Eukaryota)

chromosome organisation and biogenesis (sensu Eukaryota)

The assembly and arrangement of the eukaryotic chromosomes, structures composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information. As in, but not restricted to, the eukaryotes (Eukaryota, ncbi_taxonomy_id:2759).

Maintaining telomeric DNA is a balance between shortening, caused by the failure of normal DNA replication to complete replication of the ends, and lengthening of telomeric DNA sequences, which is dependent upon the activity of the telomerase enzyme.

The assembly and arrangement of a mitochondrion, including mitochondrial morphology and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.
