What is the official name of the TSEN54 gene?  The official name
of this gene is “TSEN54 tRNA splicing endonuclease subunit.”
TSEN54 is the gene's official symbol. The TSEN54 gene is also
known by other names, listed below.  Read more about gene names
and symbols on the About page.  What is the normal function of
the TSEN54 gene?  The TSEN54 gene provides instructions for
making one part (subunit) of an enzyme called the tRNA splicing
endonuclease complex. This complex helps process several types
of RNA molecules, which are chemical cousins of DNA.  The tRNA
splicing endonuclease complex is particularly important for the
normal processing of a form of RNA known as transfer RNA (tRNA).
tRNA molecules help assemble protein building blocks known as
amino acids into full-length proteins. However, before they can
assemble proteins, tRNAs must be processed into mature
molecules. In particular
