Structure and Functional Analysis of a Tilapia (Oreochromis

It involves transcription factors (TFs) that bind to regulatory sequences and either activate or repress gene ex-pression For repression, eukaryotes have developed various strategies involving proteins known as corepressors (1) These proteins usually do not directly interact with DNA, but are addressed to regulatory sequences by sequence

Nucleolin structure and functions

structure Ribosome biogenesis is the major function known to be associated with the nucleolus (Hadjiolov, 1985), although recent work suggest that this nuclear compartment might be involved in other cellular processes (Pederson, 1998) The nucleolus is the site of ribosomal RNA (rRNA) transcription, rRNA modiﬁcation, maturation and assembly
