The Spi-1 (PU.1) 5′ UTR regulatory element is an
RNA element found in the
5′ UTR of Spi-1
mRNA
In molecular biology, messenger ribonucleic acid (mRNA) is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene, and is read by a ribosome in the process of Protein biosynthesis, synthesizing a protein.
mRNA is ...

translation
Translation is the communication of the semantics, meaning of a #Source and target languages, source-language text by means of an Dynamic and formal equivalence, equivalent #Source and target languages, target-language text. The English la ...

Spi-1 regulates myeloid gene expression during
haemopoietic development. Mutations in this regulatory region of the 5′ UTR can lead to overexpression of
Spi-1 which has been linked to development of
leukaemia
Leukemia ( also spelled leukaemia; pronounced ) is a group of blood cancers that usually begin in the bone marrow and produce high numbers of abnormal blood cells. These blood cells are not fully developed and are called ''blasts'' or '' ...
